An independent claim is also included for a side module for a motor vehicle.

Description

The The invention relates to a motor vehicle with a power transmission element and a seat module for a motor vehicle.

In order to protect vehicle occupants from injury in the event of side collisions on a motor vehicle, the passenger compartment is usually designed to be stiff. To prevent deformation of the passenger compartment, suggests, for example, the DE 101 43 881 A1 the use of an energy absorbing element, which is mounted for use in a seat, in particular a front seat of a vehicle, arranged transversely to the direction of travel. The DE 36 07 855 A1 discloses a passenger compartment of a motor vehicle with improved side impact protection.

In contrast, the object is an improved motor vehicle and a to provide improved seat module for a motor vehicle.

The The objects underlying the invention are each with the Characteristics of the independent claims solved. Preferred embodiments of the invention are in the specified dependent claims.

The The invention relates to a motor vehicle having at least one vehicle seat, a door-side body part, a vehicle middle Body part and extending in a direction transverse to the motor vehicle Energy transfer element, wherein the energy transfer element for transmitting a side impact on the door-side body part acting compressive force on the vehicle-central body part is formed, wherein the vehicle seat separated from the power transmission element on the vehicle body is attached.

The Motor vehicle according to the invention has the advantage a high degree of injury safety of vehicle occupants, which themselves in the vehicle. By the energy transfer element In the event of a side impact, compressive forces are applied directly derived on the vehicle central body part, wherein such vehicle-center body part usually a high has mechanical stability as part of the body. Characterized in that the vehicle seat separated from the energy transmission element is attached to the vehicle body, it is ensured that an impact energy is not transmitted to the vehicle seat is, but passed on the vehicle seat on the body becomes. Thus, for example, an energy-absorbing deformation parts of the vehicle body, in particular in the area of the vehicle center Body part, take place, whereas the seating area of a passenger is substantially un influenced by such a deformation. There is no direct power transmission from the power transmission element on the vehicle seat, since the vehicle seat is not on the power transmission element is attached.

To An embodiment of the invention is the energy transmission element designed deformation stiff for a side impact. This ensures that in the seating area of the vehicle occupants due to the high rigidity of the energy transfer element no deformation of vehicle parts takes place, whereby, for example prevents a passenger from being deformed by such Vehicle parts is trapped.

To Another embodiment of the invention is on the energy transmission element motor vehicle door side further arranged a first baffle element, wherein the first baffle element for transmitting the in the Side impact acting on the door-side body part Pressure force formed on the energy transmission element is. Such a baffle element has the advantage that preferably over a large area Absorbed pressure forces and transmitted to the energy transfer element can be. This is especially useful usually a deformation is not punctiform take place in the region of the energy transfer element is, but offset.

To a further embodiment of the invention, the first baffle element further comprises a first drive element, wherein the first drive element for automatic transfer of the first impact element from a parking position into a functional position is formed in a side impact, wherein only in the functional position a positive connection between the door-side body part and the first baffle takes place. In the parking position, however is such a form-fit is not given. Seen purely visually this has the advantage that in the parking position the baffle element is not perceived by a passenger and thus the external appearance of the motor vehicle is not affected. Furthermore This avoids having the baffle element in the passenger compartment in the parking position, d. H. in the non-activated state of the drive element, protrudes. Only in the functional position finds a form fit between the door-side body part and the first Baffle element instead, allowing an effective power transmission from the door-side body part to the first impact element and from the first baffle element to the energy transfer element takes place.

According to a further embodiment of the invention, a second baffle element is further arranged on the power transmission element motor vehicle side, wherein the second baffle element for over transmission of the force acting on the door-side body part in the side impact pressure force is formed on the vehicle-central body part. In addition, the second impact element has a second drive element, wherein the second drive element is designed for automatically transferring the second impact element from a parking position into a functional position in the event of a side impact, wherein a positive connection between the vehicle-center body part and the second impact element takes place only in the functional position. Here too, what has already been said with regard to the first impact element applies, namely that a visually clean overall aesthetic impression of the motor vehicle cell results, since preferably in the parking position the first and the second impact element are not perceived by a vehicle occupant as protruding components.

To Another embodiment of the invention is the first and / or the second impact element for energy absorption in the Side impact acting on the door-side body part Impact energy formed. This is the side impact one additional absorption of the impact energy by these Baffle elements instead.

To Another embodiment of the invention is in the first and / or second drive element to an electric motor drive element and / or a pneumatic drive element and / or a pyrotechnic Drive element and / or a drive element which a transducer material having. In all cases, however, should be guaranteed be that in case of detecting a side impact or generally of a car crash in a split second divide an overpass of the first and / or second impact element from the parking into the Function position takes place.

To an embodiment of the invention are the first and the second drive element identical to each other. In other words is only for the energy transfer element a single drive element provided, which both the first and also transferred the second impact element of the parking position in the functional position.

It It should be noted that the first and / or second drive element either can be arranged on the respective impact element itself, or that two Segments of the energy transfer element via a drive element can be connected to each other. In the latter case is then at the respective end of the segments in each case the first and / or second impact element.

To a further embodiment of the invention, the vehicle central body part an energy absorbing element, wherein the energy absorption element for energy absorption in the Side impact acting on the door-side body part Impelling energy is formed. Preferably, in this case, the energy absorption element of the vehicle-center body part and the energy absorption properties of the first and / or second impact element matched. In addition, preferably a vote on the stiffness of the vehicle-center body part. Thus, for example, provided be that in case of a very strong side impact first the impact elements absorb a small part of the impact energy, wherein during this energy absorption triggering the vehicle airbags takes place. This leaves the passenger compartment within a first period, largely intact, so that a Ensures complete and unhindered deployment of the airbags is. So the airbags can be completely complete be inflated, thereby providing maximum protection of vehicle occupants to ensure. Only after this inflation of the airbags Then, in extreme cases, a deformation of the energy absorption element takes place the vehicle-center body part and thus a slight deformation the passenger cell. Nonetheless, the passenger is through the already deployed airbags sufficiently protected.

To Another embodiment of the invention is in the energy absorbing element around a honeycomb structure and / or a foam structure. For example, the energy absorbing element Foamed aluminum on.

To a further embodiment of the invention, the vehicle-central body part on a tubular shape, wherein a particularly good power dissipation due to this tubular shape on the vehicle body is possible. For example this tube form is a U-shape. Such U-shape, for example, by a transmission tunnel of the motor vehicle given.

To a further embodiment of the invention, the Vehicle seat on a seat, wherein the energy transmission element in which the seat forming seat volume extends. Preferably, the energy absorption element is as high as possible under the seat, d. H. as directly as possible at the occupant, so that is guaranteed during a side impact acting deformation forces of the motor vehicle door Passing the passenger over on the vehicle central body part can be. By the almost immediately below the vehicle occupant extending energy absorbing element is a high rigidity the passenger compartment in the knee and pelvic area of the vehicle occupant guaranteed.

According to another embodiment of the Invention, the energy transmission element extends in a stiffening tube of the motor vehicle seat. As already mentioned above, however, it is crucial here that there is no mechanical connection between the energy transmission element and the stiffening tube, ie the energy transmission element and the motor vehicle seat itself. If this were the case, in the case of a side impact and in the case of forces acting on the energy absorption element, part of these forces would be transmitted to the vehicle seat itself, which, however, is accompanied by an energy transfer of these impact forces to the passenger. Due to the "decoupling" of Energieübertragungsele element and vehicle seat thus an increased risk of injury to the vehicle occupant is prevented.

To Another embodiment of the invention is the energy transmission element movable together with the seat. This ensures that that the energy transfer element always in optimal Position relative to the seating position of the vehicle occupant is located.

To Another embodiment of the invention is at the door-side body part to a motor vehicle door and / or a motor vehicle pillar, such as a A-, B- or C-pillar and / or a roll bar. Thus, two load paths are formed in total for a side impact, namely once the load path for power transmission over the pillars of the motor vehicle to the vehicle body and on the other hand, the load path from the transmission of the load from the door and / or the columns and / or the roll bars the power transmission element and from there to the vehicle body through the vehicle central body part.

To a further embodiment of the invention, the Motor vehicle also has a side panel, wherein the side panel on the vehicle floor between the vehicle door and the the motor vehicle door facing vehicle seat is fixed, wherein the side panel at least one lateral guide element having the vehicle seat via the side panel is attached to the vehicle body, wherein the guide element for guiding a sliding movement of the vehicle seat in Longitudinal direction of the motor vehicle is formed, wherein the energy transfer element separated from the side panel runs in the side console.

Thereby the safety of a vehicle occupant is further increased. Initially forces acting on a side impact become directly over the energy transfer element derived to the vehicle body via the vehicle central body part. But finds a further deformation of the passenger compartment due an extremely strong side impact, the vehicle door, the side panel and the vehicle seat a closed power chain, which in turn is adapted to forces on the vehicle body derive.

The Use of the additional side panel also has the Advantage that between the vehicle door and the vehicle seat a closed chain of force between door, side console and seat is formed, what the rigidity of this overall composite increased in a side impact. As well as the Motor vehicle seat on the side panel is fixed and thus not more must be moved on rails, which at the vehicle floor are arranged, there is the advantage that in a side impact not acting on the vehicle seat lateral forces lead to a power transmission in the form of a leverage effect: A side impact is usually in the area of the hip or at knee height of a seated vehicle occupant, so that the forces acting on the vehicle seat there lead to a strong leverage effect on the "seat anchorages", by means of which the motor vehicle seat directly on the vehicle floor is mounted. Are however these mounting points, that is the guide elements, for the motor vehicle seat near the hip or knee area a seated vehicle occupant arranged on the vehicle seat, so This is the side impact acting on the vehicle seat leverage significantly reduced. By using the side panel, which at least has a lateral guide element leaves Such an arrangement of a motor vehicle seat attachment near a knee area or hip area realize a vehicle occupant.

typically, Side collisions at waist height of the passenger take place, so in the case of, if guide elements attached at the level of the bottom of the vehicle body are, very strong leverage on these guide rails Act. This could be the vehicle seat from his by the Guide rails caused anchorage be torn out, which would cause serious injury to a passenger. If, however, the vehicle seat is above guide rails, which are arranged immediately below the seat are attached to a side console, so leverage forces on such guide elements significantly reduced. It is important Nonetheless, in this case nonetheless, strong leverage act on the fasteners of the side panel, by means of which the side panel is attached to the vehicle body. Indeed can, as the side panel with its bottom preferably rigidly attached to the body, these fasteners be designed very stable, so also by very strong leverage no tearing out of the side panel from its attachment takes place on the vehicle body.

It It should be noted that the energy transfer element can divide into different segments, which in the transverse direction to Motor vehicle adjacent to each other, so that a relative movement of vehicle seat and side panel to each other in the vehicle longitudinal direction is possible. Preferably, however, is a continuous Energy transmission element, for example in the form of a hollow Rod or a profile carrier, in front, which is through the side panel extends therethrough. In that the energy transfer element Also on the side panel itself is not attached and only "loose" in the side panel runs, is again ensured that first, the occurring in a side impact Pushing forces transmitted to the vehicle center side body part and no direct power transfer to the side panel itself and thus takes place on the vehicle seat.

To Another embodiment of the invention is the side panel shaped so that the area between the vehicle door and the vehicle seat is filled by the side panel. This ensures that already at the beginning of a side impact a closed power chain between the vehicle door, side console and vehicle seat is present. This is a very stiff bond between the vehicle door, Side console and vehicle seat formed, reducing the overall stability the passenger compartment is further increased. Furthermore This is because the side panel is shaped so that the area between the motor vehicle door and the vehicle seat of the side panel is filled, a pollution and a visually unaesthetic overall impression of the motor vehicle insofar prevented because there are no gaps or gaps between the vehicle door and the vehicle seat arise, in which could get any objects or dirt.

To Another embodiment of the invention is the guide element for guiding the vehicle seat directly to the lower edge formed of the vehicle seat. As already mentioned above This has the advantage of being usually at height the lower edge of the vehicle seat acting side impact forces not to a strong leverage on the anchoring of the vehicle seat can lead, reducing the stability the vehicle seat connection is increased to the motor vehicle.

To a further embodiment of the invention, the Side console on the vehicle seat side facing a cushion element on and is unpadded on the side facing away from the vehicle seat.

It It should be noted that under side panel both the Side console itself as well as all on the side panel arranged elements such as a side upholstery, armrest and a Essay be understood. The fact that the side panel and thus also the side upholstery, the attachment and / or the armrest on the side facing away from the vehicle seat is unpadded, has the advantage that in the event of a side impact through the vehicle door forces acting on the side panel directly and without a deformation of the side panel from the side panel on the vehicle floor be derived. In addition, the side console with the vehicle seat a closed power chain. Through the padding on the other hand, on the side facing the vehicle seat, ensures a high level of comfort of a passenger located there. Does the passenger experience forces due to side impact pressed on the side panel, it is due to the padding between the side console and the vehicle seat an attenuation of the impact and thus a reduction the risk of injury to the vehicle occupant.

To a further embodiment of the invention, the Side panel also has a side padding on. The following is without restriction of generality, it is believed the side upholstery is an armrest. Indeed This is not mandatory, as the side padding also arranged in the z-direction above or below a typical Armauflagenposition can be, so in this case the side upholstery is not more than armrest is suitable. In this case, the side padding is used primarily a side impact protection, which in detail below explained with reference to various embodiments becomes.

in the Case of an embodiment as an armrest also results the advantage that in turn the door panel is very thin can be configured, as well as the function of the armrest in the vehicle interior, in this case on the side console, relocated becomes.

According to a further embodiment of the invention, the armrest is formed by the attachment of the side panel. This attachment is preferably displaceable relative to the motor vehicle in the longitudinal direction of the motor vehicle, wherein the underside of the side console is firmly anchored to the motor vehicle, in particular its bottom. This results in a stable connection of the side panel to the motor vehicle, but without sacrificing the comfort of a moving armrest. In addition, a moving armrest has the advantage that it is always in the same position relative to the motor vehicle seat, so that regardless of the size of the vehicle occupant, and thus the individual Sitzpositi on, the relative arrangement of the vehicle seat and armrest is always the same.

To Another embodiment of the invention is the armrest in the longitudinal direction and / or y-direction and / or in the z-direction of the motor vehicle. For example, the armrest by a rotational movement about one in the longitudinal direction of the motor vehicle extending axis in y-direction movable. Alternatively or in addition it is possible that further provided a drive element is, wherein the drive element for a movement of the armrest is formed in the longitudinal direction and / or y-direction. The Drive element is for example an automatic Movement of the armrest in the y direction towards the vehicle in the event of a crash educated. These embodiments have all together with the technical advantage that the position of an armrest relative can be individually adjusted to the vehicle occupants. The nearer while the armrest in the y-direction on the body of the vehicle occupant the lower are the acceleration paths which act on a motor vehicle occupant in a side impact. is For example, an armrest on the left side of the vehicle occupant and if a side impact from the right occurs, the vehicle occupant becomes accelerated from right to left on the armrest. Is the Way, for example by the automatic movement of the armrest reduced to zero in the y direction towards the vehicle seat in the event of a crash, so can no relative acceleration of the body of the Car occupants and the armrest take place - the Armrest thus acts in the event of a crash as a "crash pad" and Force-receiving element.

The Target, in the event of a crash, a relative movement between the armrest and Minimizing motor vehicle occupants accomplishes the present invention also by the further embodiment that the armrest variable in size in y-direction is. For example, the armrest is in size changeable in the y-direction by an inflation process. So In this case, the armrest can be in size in y direction toward the vehicle seat in particular by an automatic Inflation process to be changed in the event of a crash.

To Another embodiment of the invention is the armrest slidable by a telescopic arrangement in the z direction, wherein a End of the telescope assembly is connected to the side panel. This ensures that on the one hand an easy entry and exit process in or out of the vehicle possible is, nevertheless, not on comfort and safety at the same time Operation of the motor vehicle must be dispensed with: For example It is possible that the armrest in z-direction optimally adapted to the elbow height of the vehicle occupant can, with the elbow height usually far will be above a seat plane. So it is preferable that the armrest in the z-direction in an entry process flush closes with the seat and then automatically moved to a z-position, which is convenient for the laying on of an arm is. Moreover, by the adjustment in z-direction further secured that in the event of a side impact the Armrest as a lateral support element for the motor vehicle occupant in an optimal position in the z-direction for the vehicle occupant can be arranged.

To a further embodiment of the invention, the Side console on a running in the y direction axis of rotation, wherein the armrest by a rotational movement about this axis from a parking position can be converted into a functional position. A such rotation also serves to facilitate and exit of a passenger in the motor vehicle, since both at On as well as the exit the full door area is enabled for the entry and exit process - one Obstruction of entry and exit through protruding or protruding Parts of the armrest is prevented.

To Another embodiment of the invention is an arm about a first axis of rotation of the side panel extending in the y-direction rotatable, the arm having a second axis of rotation extending in the y-direction , wherein the armrest by a rotational movement about this in the y-direction extending second axis of rotation and a rotation of the Arms about the first axis of rotation from a parking position into a functional position can be transferred is. Here also the above applies, namely, that thus ensuring that for a single and a Exit process the full door width without a hindrance is given by substantially protruding parts of the armrest.

To Another embodiment of the invention is the armrest by a movement on a circular segment-shaped path in the x-z plane from the parking position into its functional position can be transferred. Here, too, the above applies as far as possible large release of the door surface for an entry and exit process.

According to a further embodiment of the invention, the armrest further comprises control buttons for controlling vehicle functions. In addition, since preferably the armrest is movable together with the vehicle seat, it is here ge guaranteed that in any position of the vehicle seat in an equally comfortable manner, an operation of these control buttons is guaranteed. Smaller people who prefer a different sitting position than taller people have direct access in the same way gear to these buttons.

To Another embodiment of the invention is the armrest automatically when closing the armrest assigned Motor vehicle door from the parking position into the functional position can be transferred. This ensures that the armrest as a security element is actually used in a motor vehicle as such. By automatically transferring the armrest from the parking to the functional position is always ensured that the armrest is in such a position, in which can act as a protective element in the event of a crash.

To a further embodiment of the invention, the Side console and / or the armrest an integrated airbag on.

In In another aspect, the invention relates to a seat module for a motor vehicle with at least a first vehicle seat and a first side panel, with the first side panel on the vehicle floor between the motor vehicle door and the motor vehicle door facing vehicle seat is fixed, the first side panel has at least one lateral guide element, wherein the guide element for guiding a sliding movement the vehicle seat in the longitudinal direction of the motor vehicle is formed, wherein a first energy transmission element separated in the first side panel runs, where the first energy transfer element in the transverse direction to Motor vehicle extends and for transmission in a side impact acting on a door-side body part pressure force is formed on a vehicle central body part, wherein the first vehicle seat separated from the first energy transmission element attachable to the first side panel.

This has the advantage that a module prefabricated in its entirety can be used, which only used in corresponding receptacles of the motor vehicle must become. This makes it possible, for example, depending on Comfort requirements and price range individual seating modules for To configure motor vehicles, which in one for all Vehicle classes common vehicle body can be used.

To a further embodiment of the invention, the Seat module also has a second vehicle seat, a second side panel and a center console, wherein the first and second seat consoles at opposite ends of the first and second vehicle seat are arranged, with the two vehicle seats through the center console are separated from each other, wherein the center console further guide elements to guide an individual displacement movement of the two vehicle seats in the longitudinal direction of the motor vehicle having.

Also This makes it possible to universally a motor vehicle body to provide, which equipped with different seating modules becomes. A separate assembly of vehicle seat and vehicle body is no longer necessary, resulting in a corresponding assembly process considerably accelerated.

It It should be noted that in this case the energy transfer element consistently between the two opposite ones door-side body parts can run transversely to the motor vehicle, thereby further increasing the overall stiffness of the passenger compartment becomes. Nevertheless, an energy transfer to the vehicle body in the area of the vehicle-center body part, can in the region of the vehicle-central body part, the energy transmission element have a U-shaped arch shape, and fixed in this area be connected to the vehicle body. In a transformation is also an H-shape or T-shape or the like possible.

To a further embodiment of the invention, the first and / or the second vehicle seat between the respective side panel and the center console below the seat an additional Stiffening up. This stiffening serves further to an increase in stability the passenger compartment, especially in the knee and hip area a vehicle occupant. Moreover, through the use of lateral guide elements of the side panel a housing such additional stiffening readily possible there on an attachment of the vehicle seat immediately below the seat to be dispensed with the vehicle body can. The said stiffening may be different shapes, such as a U-shape.

in the Below, preferred embodiments will be described with reference to FIG Drawings explained in more detail. Show it:

1 a schematic view of a passenger compartment,

2 another schematic side view of a passenger compartment,

3 a schematic view of a passenger compartment with a passenger,

4 another schematic view of a passenger compartment with vehicle seat and center console,

5 schematic views of driving center-wise fastenings of a power transmission element,

6 a schematic view of a seat module with side panels and a center console,

7 various schematic views of armrests for motor vehicles.

in the Following are similar elements to each other with the same Reference number marked. This is generally without limitation the Generality as assumed that when talking about armrests is, these armrests also generally replaced by "side pad" can be. It is also within the scope of the present invention possible to attach the armrest to a vehicle seat.

The 1 shows a schematic view of a passenger compartment, in which a passenger 106 located. The passenger 106 sits on the seat 104 a vehicle seat.

The passenger compartment is limited by the vehicle body 108 and the vehicle door 110 , Furthermore, in the 1 a U-shaped transmission tunnel 122 , So a vehicle-mediate body part, which provided fixed to the vehicle body 108 connected is.

The vehicle seat and thus the seat 104 are with the vehicle body 108 about fixation elements 118 connected. In these fixation elements 118 These are, for example, guide rails, which run in the longitudinal direction of the motor vehicle, ie in the X direction, and thus a sliding movement, in order to allow adjustment of the motor vehicle seat in the X direction.

In case of a side impact from the direction 116 on the car door 110 a high security of the passenger 106 ensure various safety devices are provided. On the one hand, the motor vehicle door 110 an energy absorption element 114 on, which on the side facing away from the passenger compartment of the vehicle door 110 is arranged. This absorption element can at least partially absorb impact energy. This is especially true for light side collisions from the direction 116 relevant, which causes only the area 114 the vehicle door is deformed, whereas the overall structure of the passenger compartment otherwise remains unchanged.

Further, the vehicle door points 110 a rigid surface 112 on, which is very stiff. The meaning of this area 112 is that in the event of an impact on the vehicle door 110 acting force highly effective on a power transmission element 100 can be transferred. The energy transfer element 100 preferably does not dive into the structure of the vehicle door 110 but is of the deforming and shifting vehicle door 110 in the direction 116 emotional.

At the vehicle-center body part facing the end, the energy transmission element 100 a baffle 102 on. In the 1a the baffle is located together with the energy transfer element in a parking position, in which preferably no contact between the transmission tunnel 122 and the baffle element 102 takes place. In addition, touches on the door-side body part 110 facing side, the power transmission element the vehicle door 110 not so that overall it is guaranteed that using the guide elements 118 a free movement of the vehicle seat for setting an optimal seating position in the X direction is possible.

The 1b shows the arrangement of 1a after a side impact from the direction 116 , It can be clearly seen that in the lower part of the motor vehicle door, the area 128 , the bodywork 108 and also parts of the motor vehicle door in the direction 116 deformed. It also became a driving element 120 , For example, a pyrotechnic drive element, activated due to the side impact, so that the motor vehicle door 110 facing the end of the energy transfer element previously on the surface 112 was pressed. Due to the deformation of the vehicle body and the motor vehicle door in the area 128 was then the energy transfer element on the transmission tunnel 122 pressed. By this Aufpressvorgang preferably initially finds a deformation of the baffle 102 instead, which, however, in the 1b not shown. At very high impact forces also finds a deformation of a part of the transmission tunnel 122 instead of. For effective energy absorption, the transmission tunnel has a foamed aluminum structure along the inner surface which is highly energy absorbing. This is how in the 1b visible, part of the surface of the transmission tunnel 122 in that direction 116 deformed.

Comparing the 1a and 1b , it can be seen that by the side impact, the relative position of the vehicle body 108 and motor vehicle seat with passenger 106 was not changed by the impact. The reason is that the energy transfer element 100 mechanically from the seat 104 and thus decoupled from the vehicle seat - a direct fixed mechanical connection of energy transmission element 100 and motor vehicle seat is not available. Thus transferred the energy transfer element 100 Deformation energy to other areas of the vehicle body, such as the transmission tunnel 122 whose deformation towards the occupant 106 is not critical.

Further in the 1 shown is a side airbag 126 that was triggered due to the side impact. As already mentioned above, the deformation properties of the baffle surface are preferably 102 and transmission tunnel with aluminum foam 124 designed so that in the case of a very strong side impact initially no deformation takes place inside the passenger compartment, so that the airbag 126 to protect the occupant 106 can unfold unhindered and completely. Only after the deployment of the airbag, for example within the first 30 ms of the impact, does the actual deformation of the impact element begin 102 and optionally the transmission tunnel 122 with its foamed aluminum structure 124 ,

The 2 shows a schematic side view of a passenger compartment in which a vehicle seat 204 located. The vehicle seat 204 again has a seat 104 on, with the seat 104 through a seat volume 200 is formed. Within the seat volume run stiffening tubes 202 such as knee or hip stiffening tubes. Within these stiffening tubes are the energy transfer elements 100 , As already mentioned in detail, these are energy transfer elements 100 mechanically from the stiffening tubes 202 decoupled - a direct mechanical connection between energy transfer element 100 and vehicle seat 204 not available.

The 3 shows a further schematic view of a passenger compartment. In contrast to 1 has the passenger compartment of the 3 also a side panel 300 on. This side panel is about fasteners 302 directly to the floor of the vehicle body 108 connected. The side console 300 has a lateral guide element 304 on, with the vehicle seat with its seat 104 via the side panel 300 on the vehicle body 108 is attached. The guide element 304 serves to guide a sliding movement of the vehicle seat in the longitudinal direction, ie in the X direction of the motor vehicle. Thus, the vehicle seat is not directly at the bottom of the vehicle body 108 attached. Another attachment of the vehicle seat in the form of a guide element 304 is located at the Kardantunnel 122 , The guide elements 304 are preferably formed to guide the vehicle seat directly to the lower edge of the vehicle seat. In the embodiment of 4 are the guide elements 304 therefore directly below the seat 104 , In case of a side impact from direction 116 is thus ensured that the possibly acting on the vehicle seat forces, for example by a depressed vehicle door 110 , Can not lead to a strong leverage on the guide rails, by means of which the vehicle seat to the vehicle body 108 is attached.

Typically, side collisions are in the waist of the passenger 106 take place, so in the case of, if guide elements at the level of the bottom of the vehicle body 108 are attached, very strong leverage forces act on these guide rails. Thus, the vehicle seat could be torn out of its caused by the guide rails anchoring, creating a passenger 106 would suffer severe injuries. If, however, the vehicle seat on guide rails 304 , which are just below the seat 104 are arranged, attached to a side panel, so are leverage forces on such guide elements 304 significantly reduced. It should be noted, nevertheless, in this case, strong leverage on the fasteners 302 the side panel 300 Act. However, since the side panel is preferably rigidly attached to the body with its underside, these fasteners can be designed to be very stable, so even by very strong leverage no He tear out the side panel from its attachment to the vehicle body.

The side console 300 also has an armrest 308 which is preferably coupled to the vehicle seat slidably. This ensures that in every position of the vehicle seat, the armrest 308 the same relative position to the vehicle seat and thus to the passenger 106 occupies. In the armrest 308 is also an airbag module 310 installed, so that in the event of a crash inflating the airbag, the risk of injury to the passenger 106 decreases.

In the 3 is also the energy transfer element 100 shown, which is below the seat 104 of the vehicle seat runs. In addition, the energy transfer element runs 100 in the side panel 300 without being in mechanical rigid connection with this. In case of a side impact from the direction 116 in turn automatically becomes a pyrotechnic drive element 120 triggered the baffles 306 and 102 of the energy absorption element 100 against the surface 112 the vehicle door 110 and against the transmission tunnel 122 pressed. Now finds due to strong deformation forces movement of the vehicle door in the direction 116 instead, the energy transfer element becomes 100 in the direction 116 postponed.

In addition, it can be provided in the event of a crash that the armrest 308 automatically continue to the passenger in direction 700 is pivoted so as to cause lateral stabilization of the passenger.

The 7 shows various schematic side views of motor vehicle seats, side panels movable armrests 308 exhibit. In the 7a is the armrest 308 at least in the z-direction, ie in the direction 600 , Upwardly and downwardly displaceable, so as to cover an abdominal and / or thorax region of a motor vehicle occupant. Not shown in the 7a is the possibility that the armrest 308 also optionally inflatable or in the y-direction is movable, so as to ensure a support of the abdominal and / or thorax region of a motor vehicle occupant in particular in a side impact. To move the armrest 308 For example, one serves in the 7a not shown telescopic arrangement.

Instead of the armrest 308 in the 7a in their functional position by moving in the direction 600 It is an alternative to the armrest 308 possible, an armrest 616 to provide which towards 616 be brought from their parking position parallel to the backrest of the vehicle seat in its functional position at height and parallel to the abdominal and / or thorax. In this case, the armrest is 616 However, slightly shorter in the longitudinal direction of the motor vehicle, so that this armrest when entering a passenger in the vehicle, or at the exit, does not constitute an obstacle, but only as in the 8a shown in front of the wide backrest of the vehicle seat.

The 7b shows an alternative embodiment of an armrest 308 , which for example via a telescopic device 604 in the direction 602 from their parking to their functional position can be transferred. The direction 602 represents a combined xz movement on a circular arc segment-shaped path. In the park position is preferably the armrest 308 in a position which in the 7b is shown in dashed lines. In this position, preferably the majority of the armrest is located 308 at height or below the seat 104 and also seen in the y direction in front of the backrest, so that an entry and exit process in the parked position of the armrest 308 not hindered. In the functional position, however, it is ensured that, on the one hand, a comfortable support surface for an arm of a motor vehicle occupant is provided and, on the other hand, in the event of a side impact, a slipping motion of the motor vehicle occupant on the motor vehicle door is avoided. Also for this purpose is preferably the armrest 308 movable in y-direction. Particularly preferably, this method takes place automatically in the y-direction in the event of a crash, similar to the principle of a belt tensioner, so that upon detection of a crash, for example by inflation or automatic method of armrest 308 stabilization of the motor vehicle occupant takes place in the direction of an abdominal or thorax region of a motor vehicle occupant.

The 7c shows another embodiment form, in which an armrest 308 on one arm 610 is attached. The arm 610 , is at the lower edge of the side panel at the height of the backrest of the vehicle seat via a rotation axis 606 attached so that the arm 610 around the axis of rotation running in the y-direction 606 a pivoting movement in the direction 608 , ie in the YZ plane, can perform. Further, the arm points 610 on the axis of rotation 606 opposite side another axis of rotation 612 which also runs in the y-direction of the motor vehicle. At this axis of rotation is the armrest 308 hinged. Thus, by pivoting the arm in the direction 608 around the axis 606 and by pivoting the armrest 308 around the axis 612 in the direction 608 an overpass of the armrest 308 from in the 7c dashed shown parking position can be effected in the functional position. Preferably, this is a movement of the arm 610 and the armrest 308 around the axes 606 and 612 coupled, which has the advantage that in a defined manner, a pivoting of the armrest 308 from the parking position to the functional position is possible. In addition, it is possible to automatically effect such a pivoting, for example when starting the motor vehicle.

It should be noted that such an automatic transfer of the armrest 308 from the parking to the functional position also in the 5a and 5b can be implemented. In all cases, this serves to transfer the armrest 308 from the parking to the functional position for the purpose of increased safety, since it is ensured in the event of a side impact that an acceleration of an abdominal or thorax area is shortened in the direction of the motor vehicle door, whereby the risk of injury to a vehicle occupant is significantly reduced. The transfer from the parking to the functional position is in the case preferably a component of the operation of the motor vehicle, which occupies the same importance as, for example, the wearing of a safety belt today.

Regarding 7c it should be noted that in the parking position preferably the armrest 308 completely clears a boarding area for a passenger, this boarding area is that area, which by the seat surface 104 and the area of the backrest 104 , which is the seat 104 is facing is limited. Seen in the x direction, the cross-sectional area of the backrest thus preferably covers the cross-sectional area of the armrest in the parking position 308 ,

In the 7a - 7c is also for the respective armrest 308 a control panel 618 shown, wherein the control panel for controlling various automotive functions such. As cruise control, radio and navigation system functions or window opener is formed.
