Description

BODY ASSEMBLY, BODY AND VEHICLE, AND METHOD OF MANUFACTURE THE SAME

The invention relates to a body unit comprising a body part, the body part comprising an elongate support element and at least one injection-molded part.

The invention also relates to a method for producing a body unit.

The invention also relates to a body and a vehicle as well as methods for producing the same.

The object on which the invention is based is to provide an improved body unit and/or body and/or an improved vehicle and alternatively or additionally to provide an improved method for producing a body unit and/or a body and/or a vehicle.

According to the invention, this object is achieved in that at least one injection-molded part that is molded onto the carrier element holds at least one functional element on a holding part of the functional element.

An advantage of the solution can be seen in the fact that the body part can fulfill a further function through the held functional element and because the integrally formed injection-molded part holds this functional element, a cost-effective solution is provided.

With regard to the holding part, no further details have so far been given. It is particularly favorable if the holding part is embedded in the injection-molded part, in particular in a holding component of the same. In particular, this means that the functional element is held in a particularly stable manner by embedding the holding part and is preferably also secured against twisting.

It is particularly advantageous if the holding part comprises a flange section or a plurality of flange sections, on which or on which the injection-molded part holds the functional element. For example, one flange section or several flange sections offer a large area for large-area holding by the injection-molded part, so that the injection-molded part can hold the functional element securely and well protected against twisting.

In this case, the one flange section and/or the plurality of flange sections can be designed in a wide variety of ways. The wording that at least one flange section has a feature is to be understood below as meaning that one flange section or one flange section of the plurality of flange sections has this feature or preferably some, for example all, of the plurality of flange sections have this feature.

In some advantageous embodiments, at least some of the multiple flange sections have the same combination of features.

In some favorable embodiments it is provided that at least two flange sections of the plurality of flange sections have at least one different feature, for example different combinations of features.

In particular, at least one flange section is designed as a flat flange section. It is particularly advantageous if at least one flange section has flat sides lying opposite one another, on which the injection-molded part holds the holding part and thus also the functional element. As a result, it is achieved in particular that by the large-area holding on the opposite flat sides by the injection molded part, the injection molded part holds the at least one flange section in a particularly stable manner and rotation of the same and/or bending of the connection between injection molded part and functional element can be at least reduced or even completely avoided .

It is particularly advantageous here if at least sections of the injection-molded part are integrally formed on at least one flat side, in particular on both of the opposite flat sides, so that the connection between the injection-molded part and the functional element is particularly stable.

A plurality of flange sections are preferably arranged next to one another.

At least two flange sections are preferably arranged transversely to one another, in particular at least approximately perpendicularly to one another, and in particular also arranged next to one another, as a result of which the injection-molded part holds the holding part acting in different directions and the connection thus preferably withstands a wide variety of loads.

For example, the holding part is essentially formed by the one flange section or by the plurality of flange sections.

In particularly favorable embodiments, it is provided that the holding part has at least three flange sections.

It is particularly advantageous if the at least three flange sections at least essentially form the holding part. For example, a flange section is arranged between the two other flange sections and connected to them. In particularly advantageous embodiments, it is provided that the holding part has an undercut or several undercuts, as a result of which the connection between the injection-molded part and the holding part is strengthened, for example.

In the following, the wording that at least one undercut has a feature is to be understood in particular as meaning that one undercut or one of the multiple undercuts has the feature or preferably some, for example all, of the multiple undercuts has the feature. The multiple undercuts can have the same or different combinations of features.

It is particularly advantageous if at least one undercut is encompassed by the injection-molded part and thus, in particular, undesired detachment of the functional element is at least made more difficult.

The at least one rear section can relate to a wide variety of directions.

It is advantageous if at least one undercut is transverse, for example at least approximately perpendicular, to a direction of a longitudinal extent of the carrier element, so that breaking off the functional element and/or relative rotation with respect to the longitudinal direction is at least made more difficult.

In particularly favorable embodiments, it is provided that at least one undercut is an undercut in relation to a direction oriented from the holding part to the carrier element, which in particular strengthens holding of the functional element by the injection-molded part with regard to tensile loading. It is favorable if the holding part has at least one wall section which runs at least approximately parallel to the longitudinal extent of the carrier element.

For example, the wall section is also a flange section.

In favorable embodiments, the wall section is a section of a shaped element of the holding part, which is in particular formed onto at least one flange section or is formed from at least one flange section.

For example, the shaped element is a rib and/or a depression or indentation and/or a molded projection or a shaped element molded or formed with a different shape.

In particular, the at least one wall section has a side facing away from the carrier element and at least one section of the injection molded part covers this side facing away at least partially, in particular over the entire surface. For example, the covering section of the injection-molded part is molded onto the side facing away from the wall section.

One advantage of this is, for example, that the functional element is stably supported by the at least partial covering of the side facing away from the wall section and is held in the direction of the carrier element.

For example, a side of the wall section opposite the side facing away is also covered with a section of the injection molded part, so that the wall section is preferably embedded in the injection molded part and, in particular, a stable mounting of the functional element under tension and against pressure is provided. In particularly favorable embodiments it is provided that the holding part has an indentation or a plurality of indentations.

Below, the wording that at least one indentation has a feature is to be understood in particular as meaning that the one indentation or one of the multiple indentations has this feature or that preferably some, for example all of the multiple indentations have this feature. In particular, at least some of the multiple indentations have the same feature or the same combination of features. In some favorable embodiments, at least some of the multiple indentations have different features or different combinations of features.

It is particularly advantageous if the injection-molded part engages at least in one indentation with an engaging section, a particularly stable holding being realized in particular as a result of this engagement.

It is particularly favorable if the inner walls of at least one indentation are covered over the entire area by the corresponding engaging section of the injection-molded part, thereby realizing stable holding in several directions and preferably also against twisting.

Preferably, the engaging portion is molded onto the indentation and its inner walls.

In particular, at least one indentation extends from an outgoing side into the holding part up to a bottom section. In particular, sections with the inner walls extend from the outgoing side to the bottom section and the inner walls form, for example, a peripheral delimitation of the indentation in relation to the direction of extension. For example, the base section is arranged in the holding part, in particular between the outgoing side of the holding part and a side opposite thereto.

In favorable embodiments, the base section forms the side opposite the outgoing side, so that, for example, the indentation extends from the outgoing side into the holding part to the opposite side, but is only open on the outgoing side and closed on the opposite side.

In particularly advantageous embodiments, it is provided that the base section protrudes beyond the side opposite the outgoing side, so that in particular the indentation partially protrudes beyond the opposite side. For example, a deep indentation is formed as a result and the deeply engaging section of the injection-molded part can hold it particularly well.

A side of the indentation opposite the outgoing side is preferably covered by a section of the injection-molded part, in particular this section is formed on the opposite side. The indentation is thus advantageously encompassed on both sides by the injection-molded part, as a result of which, for example, tensile and/or pressure loads and/or twisting can be withstood.

It is particularly advantageous if the part of the at least one indentation that protrudes beyond the opposite side is covered on both sides over the entire area by the injection-molded part and is thus held particularly stable as a result.

The one indentation or the multiple indentations can be formed at different points of the holding part. It is particularly advantageous if at least one indentation is formed in at least one flange section.

In particularly favorable embodiments, the holding part has an opening or several openings.

In the following, the wording that at least one opening has a feature means in particular that one opening or one opening of the multiple openings has this feature or that preferably some, for example all, of the multiple openings have this feature. For example, some of the multiple openings have the same feature or the same combination of features, and in some advantageous embodiments, some of the multiple openings have different features.

In particular, the injection-molded part reaches through at least one opening, so that a particularly stable mount is provided.

In particular, material of the injection molded part completely fills at least one opening.

In particular, an opening opens on a respective side of the holding part with a respective opening and extends continuously from one opening to the other opening.

In particular, a respective breakthrough opening of the at least one breakthrough is bordered by a respective edge section of the holding part. It is particularly advantageous if the edge sections are at least partially, preferably over the entire surface, covered by the injection molded part and, in particular, these covering sections are molded onto the section of the injection molded part that engages in the opening. The engaging section is thus held in a particularly stable manner and good fixation of the functional element is advantageously provided.

One opening or several openings can be provided at different points of the holding part.

It is favorable if at least one flange section has at least one opening, in particular has a large number of openings.

In particularly advantageous embodiments, it is provided that at least one indentation has at least one opening. As a result, for example, the stable holding of the indentation is additionally reinforced by the additional penetration of the opening.

For example, the at least one opening is formed in an inner wall of the indentation.

It is particularly favorable if the at least one opening is formed in the base section of the at least one indentation.

It is particularly favorable if at least one flange section has a large number of openings and one or more indentations, each with at least one opening.

For example, at least one opening is an opening that is wide across the retaining element, based on its direction of extension. In other advantageous embodiments, at least one opening is narrow, so that its extent transversely to its extent through the holding part is at least approximately of the same order of magnitude as an extent between the two openings, and in particular is less than five times the last-mentioned extent, for example at least the expansions are approximately the same size, or the transverse expansion is smaller than the expansion between the breakthrough openings.

In particular, the engaging section of the injection molded part is designed like a pin.

For example, the holding part comprises a projection or a plurality of projections.

In the following, the wording that at least one projection has a feature is to be understood in particular as meaning that the one projection or one of the plurality of projections has the feature or that preferably some, for example all, of the projections have this feature.

For example, some of the plurality of protrusions have the same feature or combination of features, with some advantageous embodiments some of the plurality of protrusions having different features or combinations of features.

In particular, at least one projection is at least partially encompassed by the injection-molded part, so that stable mounting is provided. It is preferably provided that the at least one projection is encompassed by the injection-molded part over its entire surface. For example, at least one projection is designed as a shaped element and/or as a protruding part of an indentation, so that reference is made to the explanations above with regard to further advantageous designs, it being advantageously provided that at least one projection has at least one of the features explained above.

It is particularly advantageous if the holding part comprises one holding rib or a plurality of holding ribs.

An advantage of this is, for example, that the one retaining rib or the multiple retaining ribs increase the stability of the retaining part and, for example, improve the connection between the retaining part and the injection-molded part.

In the following, the wording that at least one retaining rib has a feature is to be understood to mean in particular that the one retaining rib or one of the plurality of retaining ribs has the feature, preferably some, for example all, of the retaining ribs have the feature.

In particular, at least some of the plurality of retaining ribs have the same feature or the same combination of features, with some retaining ribs having different features or combinations of features, for example.

In particular, it is provided that the injection-molded part encompasses at least one retaining rib. In this way, it is achieved in particular that the injection-molded part holds the holding part in place at a stabilized section.

In particular, at least one retaining rib comprises a rib section or a plurality of rib sections. It is favorable if at least one rib section is designed to run in a direction running transversely to the longitudinal extension of the carrier element. The injection-molded part preferably encompasses this rib section and, in particular, the risk of the functional element twisting or shifting transversely to the longitudinal extension of the carrier element is at least reduced.

It is particularly advantageous if at least one holding rib has at least one rib section which is designed to run in a direction running at least approximately parallel to the longitudinal extent of the carrier element. In particular, the injection-molded part encompasses this rib section and, for example, thereby keeps the functional element essentially at a predefined distance from the carrier element.

It is particularly advantageous if at least one retaining rib has at least two rib sections which run transversely to one another and which are in particular arranged on one another. The injection-molded part preferably encompasses these transverse rib sections and thus holds the functional element in place with respect to a number of directions.

For example, one of the two transverse rib sections is arranged in a central area of the other rib section, so that the retaining rib has a T-shaped cross section in this area.

It is particularly favorable if at least one retaining rib has at least one undercut, reference being made to the above statements with regard to advantageous statements in this regard.

For example, at least one retaining rib forms at least one wall section, as explained above, so that reference is made to the explanations above. In preferred embodiments it is provided that the holding part has at least one receiving space in which the injection-molded part engages. In particular, this achieves stable fixing of the holding part by the injection-molded part.

In particular, the holding part has one receiving space or several receiving spaces, with the wording that at least one receiving space has a feature below being understood to mean in particular that one receiving space or one of the several receiving spaces has this feature or that some, for example all, of the several Recording rooms have this feature. If there are several receiving spaces, they can have the same feature or the same combination of features and, for example, have one or more different features.

It is particularly favorable if the at least one receiving space is at least partially delimited by at least one flange section.

For example, three flange sections delimit the receiving space on three sides.

It is particularly favorable if the at least one receiving space has at least one indentation.

For example, at least one indentation is designed to extend away from the receiving space.

In advantageous embodiments it is provided that at least one indentation protrudes into the receiving space. In particular, the outgoing side of the indentation is therefore arranged on a side opposite the receiving space and the indentation protrudes into the receiving space. Provision is preferably made for at least one section of the holding part delimiting the receiving space, for example a flange section, to have at least one opening, as a result of which, for example, the fixation in the receiving space by the injection-molded part is further reinforced.

It is particularly advantageous if at least one holding rib is arranged in the at least one receiving space. In particular, this strengthens the fixing connection between the injection molded part and the holding part. For example, this design is also favorable since the holding rib is arranged in the receiving space in a space-saving manner and, in particular, does not protrude beyond an outer contour of the functional element.

Alternatively or additionally, the above-mentioned object on which the invention is based is also achieved in that at least one injection-molded part forms at least one functional element in a body unit which in particular comprises one or more of the features explained above.

In particular, one advantage of this can be seen in the fact that the body component is equipped with at least one functional element in a cost-effective and stable manner.

It is particularly favorable if the at least one injection-molded part forming at least one functional element is molded onto the carrier element and the functional element is thus advantageously arranged firmly on the carrier element in a structurally simple manner and in a stable manner.

For example, the at least one injection-molded part forming at least one functional element has one or more of the features and/or design options explained above, as far as this is possible. The at least one injection molded part preferably has a holding component with which the functional element is arranged on the carrier element. Depending on the solution, provision is made in particular for the holding component and the functional element to be formed in one piece by the at least one injection-molded part, or for the holding component to hold a separate functional element.

The holding component is preferably formed onto the carrier element.

With regard to the functional element, no further details have been given so far.

For example, the functional element is a functional element of a vehicle functional unit.

In other advantageous embodiments, the functional element is, for example, a functional element of an equipment unit in the vehicle.

It is particularly favorable when the functional element is designed as a fastening element.

In particular, it is provided in preferred embodiments that the functional element is designed for fastening a vehicle functional unit and/or an equipment unit.

For example, what is achieved with this solution is that the vehicle functional unit can be stably attached to the body component and at the same time a cost-effective and weight-saving design solution is provided because the functional element is held and/or formed by the injection molded part. For example, it is provided, particularly in embodiments in which the functional element is held by the injection-molded part, that the vehicle functional unit can be and is fastened both to the functional element and to a holding component of the injection-molded part, so that a particularly stable fastening is achieved in particular. An equipment unit can also be attached in this way.

In particular, in the case of a body, in particular a motor vehicle, with such a body unit, it is provided that the vehicle functional unit and/or equipment unit is attached at least to the functional element and, for example, also to the injection-molded part, in particular to the holding component thereof.

In particular, the vehicle functional unit is a functional unit which is necessary for the proper functioning and driving of a vehicle with the body unit.

For example, the vehicle functional unit is a drive unit of a vehicle or part thereof.

In some particularly favorable embodiments, it is provided that the vehicle functional unit is at least part of a steering system of a vehicle, for example at least part of a steering column of the steering system.

In some advantageous embodiments, the vehicle functional unit is at least part of an occupant protection system, for example an airbag system.

Alternatively or additionally, in advantageous embodiments, it is provided that the functional element is designed for attachment to a further body component. In particular, it is provided that the body unit comprises at least one further body component and that preferably the at least one further body component is attached to the functional element.

In this way, for example, a stable attachment of the body components is achieved and the injection-molded part advantageously enables the attachment to be inexpensive and lightweight.

With regard to an arrangement of the functional element, no further details have so far been given.

In different embodiments, the functional element can be arranged in different positions relative to the carrier element.

In some advantageous embodiments, it is provided that the functional element is arranged in front of the carrier element, at least in one operating state in relation to a longitudinal direction of the vehicle.

In particular, the vehicle longitudinal direction corresponds at least approximately to a direction of travel of a vehicle with the body unit when driving straight ahead.

Above and below, the wording that a feature is realized at least in one operating state is to be understood in particular as meaning that in a properly assembled body, in particular in a properly assembled vehicle, this feature is realized with the body unit and that the body unit is designed in such a way that when properly installed, this feature is realized. It is particularly favorable if the functional element is arranged in a front area of a body, in particular of a vehicle, at least in one operating state. In particular, this is favorable in order to fulfill the proper function in this area.

In particular, the front area is arranged in front of a cockpit area and in particular in front of a passenger compartment with respect to the longitudinal direction of the vehicle.

The cockpit area is arranged in particular in the passenger compartment and in particular that area which is intended for the driver and in which, for example, the driver's seat and control and/or operating elements for the driver, for example a steering wheel, are arranged.

In some particularly advantageous embodiments, it is provided that the at least one further body component is a body component arranged between the front area and the cockpit area, in particular an end wall arranged between them, which separates the cockpit area from the front area, for example.

In particular, the body component has, on a side facing the cockpit area at least in one operating state, one or more mounting points which are designed for fastening control and/or operating elements for a driver and to which, in particular when the vehicle is in a fully assembled state, control and/or or controls are attached.

In some favorable embodiments, the functional element is arranged below the carrier element, at least in one operating state.

In some embodiments, the functional element is arranged on a side of the carrier element that faces a roadway at least in one operating state. This is favorable, for example, in order to enable a connection to and/or attachment to a floor structure of a body.

In particular, in such embodiments, the at least one further body component is a floor construction of the body or at least a part thereof.

The functional element can be made from a wide variety of materials.

In some advantageous embodiments it is provided that the functional element is formed at least partially, for example at least the holding part and/or a functional part, from a material comprising a metal. In particular, essentially the entire functional element is formed from a material comprising a metal.

It is particularly favorable if at least the holding part and/or a functional part, in particular the entire functional element, is made of metal.

This provides a particularly stable and resistant functional element which, in particular as a fastening element, can withstand loads such as vibrations during operation of the vehicle and/or impact effects in the event of a vehicle accident in a particularly favorable manner and can preferably withstand them essentially without damage.

It is particularly favorable that with the functional element of stable design, the possibly damaging effects can be absorbed and at least reduced, and by holding the functional element by the injection molded part, a light and cost-effective solution is nevertheless implemented. For example, the metal includes or the metal is a steel.

In favorable embodiments it is provided that the metal comprises at least one light metal or is a light metal, the light metal comprising or being aluminum and/or magnesium, for example.

In some preferred embodiments it is provided that the functional element is formed at least partially, for example at least the holding part and/or a functional part, from a material comprising a plastic, in particular substantially the entire functional element is formed from a material comprising a plastic.

For example, at least the holding part and/or a functional part, in particular the entire functional element, is essentially made of a plastic.

In particular, this is the case with solutions in which the injection-molded part forms the at least one functional element, but it can also be provided that the injection-molded part holds a functional element made of a material comprising a plastic.

It is particularly favorable if the functional element is at least partially fiber-reinforced. This can be provided for functional elements made of different materials and the fiber reinforcement can be provided by fibers embedded in the material of the functional element or by a fiber-encompassing reinforcing layer, as will be explained in more detail below.

In some favorable embodiments it is provided that the functional element is at least partially formed from a composite material, for example at least the holding part and/or a functional part, in particular the entire functional element. For example, the composite is a fiber-reinforced composite.

Alternatively or additionally, the above-mentioned object on which the invention is based is also achieved in that in a body unit, which in particular comprises one or more of the features explained above, at least one injection-molded part comprises a reinforcement component and the reinforcement component reinforces the carrier element.

In particular, an advantage of this can be seen in the fact that the carrier element can be reinforced in a structurally favorable manner by the reinforcement component and the reinforcement can be carried out at reduced costs by forming the reinforcement component with the injection-molded part.

For example, due to the additional reinforcement, the carrier element can be made more material-saving and weight-saving, without this being at the expense of stability.

For example, the reinforcement component extends at least in sections along the carrier element, in particular at least approximately along at least one third, preferably at least along half, of the longitudinal extent of the carrier element. It is particularly favorable if the reinforcement component extends at least approximately along the entire length of the carrier element.

In particular, the reinforcement component extends along a section or several sections of the carrier element on which functional elements or functional units or equipment units or the like are arranged on the carrier element in order to reinforce these more heavily stressed sections of the carrier element. In some favorable embodiments it is provided that the reinforcement component extends at least along a driver-side section of the carrier element, which is related at least to one operating state, since this section is typically subjected to greater stress.

In particular, the driver-side section of the carrier element is a section of the carrier element that is assigned to a driver's side of the body.

In the case of particularly advantageous embodiments, it is provided that at least one injection-molded part comprises a reinforcing rib or a plurality of reinforcing ribs.

An advantage of this can be seen in the fact that the injection-molded part is reinforced by the one reinforcing rib or by the plurality of reinforcing ribs and is therefore more stable.

Below, the wording that at least one reinforcing rib has a feature is to be understood in particular as meaning that the one reinforcing rib or one of the multiple reinforcing ribs has the feature or that preferably at least some, for example all, of the multiple reinforcing ribs have the feature.

In the case of the plurality of reinforcing ribs, it is preferably provided that at least some of the plurality of reinforcing ribs have the same feature or the same combination of features.

In order to fulfill different functions and/or have a different reinforcing effect, it is advantageous if some of the reinforcing ribs have a different feature or a different combination of features. In some advantageous embodiments, the holding component of the injection-molded part has at least one reinforcing rib, and this at least one reinforcing rib reinforces the holding component.

In particular, at least one reinforcement rib reinforces the carrier element, at least this one reinforcement rib being part of the reinforcement component.

An advantage of this can be seen in the fact that this additional reinforcement provides a particularly stable body component.

The one reinforcing rib or the several reinforcing ribs can be designed in many different ways.

It is particularly favorable if at least one reinforcing rib at least partially encompasses the carrier element on the peripheral side. In particular, the circumferential embracing is related to a longitudinal extension of the carrier element, so that in particular the circumferentially embracing reinforcing rib runs transversely to the longitudinal extension of the carrier element.

For example, the carrier element has a curved area.

It is particularly advantageous if at least one reinforcing rib is configured to run at least in the curved region of the support element and thus preferably reinforces the curved region.

For example, this reinforcing rib runs transversely to a direction of curvature of the curved region.

It is advantageous if this at least one reinforcing rib is designed to run at least approximately in the direction of the direction of curvature. It is particularly favorable if at least one reinforcing rib is closed on the peripheral side and runs around the carrier element.

Provision is preferably made for at least two reinforcement ribs to be formed running transversely to one another, as a result of which the stability, for example of the holding component and/or the carrier element with the reinforcement component, is increased in particular.

It is particularly favorable if at least two reinforcing ribs, for example two reinforcing ribs running transversely to one another, are designed to cross one another.

It is particularly advantageous if at least some of the reinforcement ribs of the plurality of reinforcement ribs are designed in the manner of a truss and, in particular, develop a high stability effect as a result.

In some particularly preferred embodiments it is provided that at least one reinforcement rib is formed to run longitudinally along a longitudinal section of the carrier element.

It is preferably provided that at least one reinforcing rib is arranged in an inner region of the carrier element, and the carrier element is thus reinforced in a particularly favorable manner, in particular in a space-saving manner.

In particularly advantageous embodiments, it is provided that at least some reinforcement ribs running transversely to one another and/or crossing one another are arranged in the inner area of the carrier element.

In some embodiments it is provided that a number density of reinforcing ribs per unit length, in particular along the longitudinal extent of the carrier element, is constant in individual sections. It is particularly preferred if the number density of reinforcing ribs per unit length, in particular along the longitudinal extent of the carrier element, varies, so that sections in particular that require special reinforcement are particularly reinforced and other sections have fewer reinforcing ribs, thereby simplifying the manufacture of the body component in this area.

With regard to configurations of the carrier element, no further details have so far been given.

Alternatively or additionally, the above-mentioned object is also achieved in a body unit, which in particular has one or more of the features explained above, in that the carrier element has one passage or several passages and that the at least one injection-molded part engages in at least one passage.

In particular, the fact that the injection-molded part reaches into at least one passage means that a connection between the injection-molded part and the carrier element is particularly stable. In particular, the injection-molded part and, for example, also the functional element are held securely on the carrier element as a result.

Above and below, the wording that at least one passage has a feature or in which a feature is implemented means in particular that the one passage or one of the multiple passages has this feature or that at least some, for example all, of the multiple passages have this Have feature or in this or these, the feature is realized.

In particular, at least some of the multiple passages have the same feature or the same combination of features. In some embodiments, it is beneficial if at least some of the passageways have a different feature or different combinations of features.

In particular, it is provided that at least one passage is formed running through the carrier element transversely to the longitudinal extension thereof.

It is particularly advantageous if, in at least one passage, the injection-molded part extends completely through it, and a particularly stable fixation is thus achieved in particular.

It is particularly favorable if, in at least one passage, a section of the injection-molded part that engages in the passage is arranged, in particular directly, on a reinforcing rib of the injection-molded part. For example, the engaging portion is thereby additionally strengthened.

It is particularly advantageous if, in at least one passage, a reinforcing rib of the injection-molded part is configured to run over a through-opening of the passage.

In particular, in the case of the at least one reinforcing rib configured to run over a through-opening, a section of the injection-molded part that engages into the through-opening is integrally formed on a section of the same that runs over the through-opening.

It is particularly favorable if, in at least one passage, the section of the injection-molded part that extends through the passage is molded onto a reinforcing rib at its respective ends in the region of a corresponding passage opening.

With regard to a design of the carrier element, no further details have been given so far. Alternatively or additionally, the object mentioned at the outset is also achieved in the case of a body unit, which in particular has one or more of the features explained above, in that the carrier element comprises a plurality of longitudinal sections, with at least two longitudinal sections extending longitudinally at least approximately parallel to one another and transversely to their longitudinal extent are spaced apart and at least in sections an inner region of the carrier element is defined between the at least two longitudinal sections.

For example, an advantage of this can be seen that with the at least two longitudinal sections and the inner area between them, a stable and at the same time weight-saving carrier element for the body component is realized.

In particular, the inner area extends at least approximately along the entire longitudinal extension of the at least two longitudinal sections.

The inner area is preferably a hollow inner area, so that the weight saving is realized in a particularly favorable manner.

It is particularly advantageous if the carrier element comprises at least one further longitudinal section and this at least one further longitudinal section connects the at least two longitudinal sections spaced apart from one another on one side of the inner region.

The at least one further longitudinal section is preferably formed onto the two longitudinal sections spaced apart from one another. In particular, this provides a stable and weight-saving carrier element.

A body component 210, which is shown by way of example in FIGS. 2 to 11, comprises an elongate support element 212 and at least one injection-molded part 214, preferably molded onto the support element 212.

In this exemplary embodiment, the body component 210 extends between the A-pillar supports 124a, b and is attached to them and to a body substructure 136 .

In particular, body component 210 is for attaching functional vehicle units, for example a steering column, and for attaching control units, for example, by means of which a driver of the vehicle can control the vehicle and, for example, units of its equipment, for example an air conditioning system and/or an audio system and/or a navigation system can, provided.

In variants of the exemplary embodiment, the body component 210 can also have additional and/or alternative functions and/or be arranged in a different area of the body and attached to other body components. The body component 210 extends essentially longitudinally along a component axis 218, with individual components thereof, for example the injection molded part 214, extending transversely to the component axis 218 from the essentially longitudinally extending basic structure of the body component 210.

The component axis 218 is essentially defined by the carrier element 212, which extends essentially along it with a longitudinal extent.

For example, the carrier element 212 is a metallic carrier element.

The carrier element 212 comprises a plurality of longitudinal sections 222, 224, 226, which extend along the component axis 218 at least between two opposite longitudinal ends 215 and 217 of the body component 210 along the component axis 218.

Preferably, the longitudinal sections 222, 224, 226 are essentially planar along their length, for example, planar throughout, or planar along most of the length.

For example, a single or stepped portion 238 is provided between planar portions. In particular, a longitudinal extent of the step section 238 is significantly smaller than the longitudinal extent of the longitudinal section.

Preferably, the carrier element 212 has an open cross-sectional profile, in particular a C-profile, transverse to its longitudinal extent, in particular with respect to a cross-section running at least approximately perpendicularly to the component axis 218, as shown by way of example in FIGS. Two longitudinal sections, here longitudinal sections 222 and 224, run essentially parallel to one another and are spaced apart from one another transversely to the axial direction of component axis 218, so that corresponding inner flat sides thereof face one another and partially delimit a hollow inner region 242 of carrier element 212.

Another longitudinal section, here the longitudinal section 226, connects the two spaced-apart longitudinal sections 222, 224 and is formed onto them, for example in a respective curved region 246, 248, and delimits the inner region 242 transversely to the component axis 218 and transversely to the direction in which the two spaced longitudinal sections 222 and 224 delimit the inner region 242.

Thus, interior region 242 is open to one side 252 , open side 252 being located opposite connecting longitudinal section 226 and bounded by spaced longitudinal sections 222 and 224 .

The injection-molded part 214, which is in particular one-piece, has a reinforcement component 272, which is injection-molded directly onto the carrier element 212 and reinforces it.

The reinforcing component 272 includes a plurality of reinforcing ribs 274, 276, 278.

Some of the reinforcing ribs, here reinforcing ribs 274, preferably run along the outside of support element 212 along the circumference thereof and, for example, transversely and/or at least approximately perpendicularly to component axis 218 and preferably run over all longitudinal sections 222, 224, 226, for example from an edge of the opened side 252 along the circumference of the support element 212 to the other edge of the opened side 252. In particular, some of the reinforcement ribs, here the reinforcement ribs 276, run longitudinally, i.e. in particular at least approximately parallel to the component axis 218, along an edge of the open side 252 and are preferably connected to the circumferential reinforcement ribs 274 at contact points 275.

For example, in at least some of the circumferential reinforcement ribs 274 corresponding inner reinforcement ribs 248 are arranged, which run on the inner side along the piece of the carrier element 212 encompassed by the outer reinforcement rib 274 .

Some of the reinforcement ribs, here in particular the circumferential reinforcement ribs 274 and edge reinforcement ribs 276, are of linear design, with other reinforcement ribs, here in particular the inner reinforcement ribs 278, being of flat design.

In particular, the linear reinforcing ribs have a cross section transverse to their longitudinal extent, the extent of which is at least approximately the same in mutually perpendicular directions. In the case of flat reinforcing ribs, their cross-section extends transversely to their longitudinal extension in one direction that is significantly larger, for example at least five times larger, in particular at least ten times larger, than an extension in a direction at least approximately perpendicular to the one direction.

For example, at least some of the inside reinforcing ribs 278 extend flatly from the open side 252 to the longitudinal section 226 opposite the open side 252 and transversely thereto from one of the spaced-apart longitudinal sections 222, 224 to the other of the two spaced-apart longitudinal sections 224, 222.

The carrier element 212 preferably has small passages 282 along its longitudinal sections 222, 224, 226, with the reinforcement component 272 of the injection molded part 214 reaching through the passages 282 with pin elements, with the pin elements preferably being attached at their respective ends to an external reinforcement rib, here for example to the peripheral reinforcing ribs 274, and are formed on the inside of the internal reinforcing ribs 278.

In particular, at least some of the reinforcing ribs extend at least between two passages 282.

Preferably, at least some of the outboard reinforcing ribs 274 extend from a passage 282 in one of the spaced longitudinal sections 222, 224 along the perimeter of the support member 212 at least to a passage in the other of the spaced longitudinal sections 224, 222.

For example, at least some of the internal reinforcement ribs 278 extend at least between two passages 282 in, for example, the two spaced longitudinal sections 222, 224. For example, at least one longitudinal section, here the connecting longitudinal section 226, has openings 284, which are bordered and reinforced by sections of the reinforcement component 272 bordering the opening.

At its longitudinal ends 215 and 217, the body component 210 has flange bodies 312 and 314 formed by the carrier element 212 and the injection-molded part 214 for attachment to other components of the body, as shown in FIGS. 6 and 8 by way of example.

In this case, the mold units 612, 614 have mold recesses which, in particular when assembled, essentially form the shape of the at least one injection-molded part 210 and optionally other injection-molded parts.

In the method, prior to injection molding, inserts are placed in at least some mold recesses, for example mold recess 622 of mold unit 612, which inserts form elements and/or components of body part 210, such as metal support element 212 and/or functional element 410, in particular metal, as shown in the example as shown in FIG.

Once the inserts have been inserted into their corresponding mold recesses, the mold units that can be moved relative to one another are moved into position relative to one another in such a way that the inserts are arranged in the relative positions intended for body component 210, shown by way of example in Fig. 13.

The functional element 410′ comprises in particular functional parts which are formed, for example, by the injection molded part 214′ and/or are individual separate parts which are connected to the injection molded part 214′ as inserts, in particular during the injection molding process. Otherwise, with regard to the function and the functional parts of the functional element 410′, reference is made to the explanations in connection with the first exemplary embodiment. The holding component 414 ′ is in particular formed in one piece with the functional element 410 ′ and the reinforcement component 272 . For example, it also has reinforcing ribs and/or bracing ribs.

Otherwise, the body component 210 ′ of the second exemplary embodiment is designed at least essentially with its elements and features like the body component of the first exemplary embodiment, so that, in order to avoid repetition, reference is made in full to the explanations in connection with the first exemplary embodiment.

In variants of the first and/or second exemplary embodiment, the carrier element 212 is formed partially or entirely from the injection-molded part 214, 214', as illustrated in FIG. 17 by way of example.

In particular, in these variants, the body component (210, 210') is essentially designed as an injection molded part. In some variations, the injection molded part is formed from a plastic, such as a high-strength plastic.

In other variations, the injection-molded part 214, 214' is made of several plastics, with the injection-molded part being produced in a multi-component injection-molding process and thus, for example, particularly heavily stressed areas of the injection-molded part, such as at least sections of the support element, for example at least the driver-side section, are formed with a high-strength plastic and less heavily stressed areas, such as sections for attaching equipment units, are formed with a cheaper plastic.

The rest of the design in these variants is as explained above in connection with the first and second exemplary embodiments, so that reference is made to this embodiment in its entirety.

In further variants of the first or second exemplary embodiment, which are shown by way of example in FIG. 18, at least one element and/or one component of the body part 210, 210' is fiber-reinforced.

In particular, the carrier element 212 and the injection-molded part 214, 214' are fiber-reinforced.

In this case, this fiber reinforcement can be formed both by the fiber-reinforced material and by the support, which extends along the corresponding section or the longitudinal extension.

The fibers are preferably arranged in layers. In particular, the fibers are arranged partly unidirectionally and partly intertwined in a braid in order to have a reinforcing effect preferably along load paths.

In the variants, the injection-molded part 214, 214', in particular its holding component and/or its reinforcement component, is also fiber-reinforced in a corresponding manner.

For example, the support is provided as an insert in an injection molding process. The functional element 410, 410' is also correspondingly fiber-reinforced in some of these variants.

Otherwise, these variants are at least essentially the same as the exemplary embodiments explained above and their variants, so that reference is made in full to the above statements.

In particular, the features and configurations of the various exemplary embodiments and variants thereof can essentially be combined with one another.
