Description

The invention relates to an occupant protection device for a vehicle, wherein the vehicle has a first row of seats, comprising at least one driver and / or a passenger seat and wherein the vehicle has a rear row of seats, which is opposite to a direction of travel of the vehicle, behind the first row of seats in the vehicle is arranged with a first airbag system for protecting an occupant on a seat of the first row of seats. The first airbag system includes a three-zone airbag having a first zone, a second zone, and a third zone, the first zone protecting the pelvis, the second chest protecting the thorax, and the third protecting the head of the occupant is. The invention also relates to an airbag system and a vehicle with the occupant protection device.

Occupant protection systems are installed in many vehicles to provide side impact protection to occupants in a front and / or rear seat. In many cases, they comprise one or more airbags which are designed to protect a pelvic and / or thoracic region and / or a head region of the occupants. Often they are laterally in a backrest of the front or rear seat or in a vehicle side, z. B. under a door trim integrated.

To protect a head region of the occupants on a front and / or rear seat, a so-called curtain airbag is often arranged in a lateral roof area in the vehicle, which usually extends over both side windows of a vehicle side.

Furthermore, side impact protection devices have become known which comprise an airbag with at least two chambers.

In Scripture DE 10 2005 050 935 A1 , which is probably the closest prior art, a side impact protection device is described in which an airbag is disposed in a deployed state between the front seat and a window cutout of the vehicle side. The airbag has at least two chambers, wherein the first chamber is designed to protect a head region and / or a thorax region of an occupant and in the unfolded state partially or completely covers the window cutout. The second chamber is located in the thorax area of the occupant and may extend to the pelvic area to provide protection to the thorax and / or pelvic area of the occupant.

The invention has for its object to provide an occupant protection device, an airbag system or a vehicle with the occupant protection device, which ensures a sufficient protective effect and is also designed to be cost-effective and weight-saving.

This object is achieved by an occupant protection device having the features of claim 1, an airbag system having the features of claim 10 and a vehicle having the occupant protection device having the features of claim 15.

Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and / or the accompanying figures.

According to the invention, an occupant protection device for a vehicle, in particular for a sedan, is proposed. Preferably, the occupant protection device is designed as a side impact protection system and serves to ensure the protection of occupants in the event of an accident.

The vehicle has a first row of seats, which comprises at least one driver and / or a front passenger seat, and a rear row of seats, which is arranged opposite to a direction of travel of the vehicle, behind the first row of seats in the vehicle. In particular, the first row of seats comprises front seats and the second row of seats rear seats of the vehicle. Optionally, the rear row may also be formed as a third, fourth or further row.

The occupant protection device has a first airbag system for protecting an occupant on a seat of the first row of seats. In particular, it is suitable and / or designed to protect the occupants in a side impact from injury.

The first airbag system comprises a three-zone airbag having a first zone, a second zone, and a third zone, the first zone protecting the pelvis (the pelvis), the second zone protecting the thorax (upper body), and the third Zone is designed to protect the head of an occupant. In the following, the first zone is called the pelvic zone, the second zone is the thorax zone and the third zone is the head zone.

Preferably, the first airbag system comprises one or more gas generators, which are adapted to fill the three-zone airbag with gas in an accident, in particular in a side impact of the vehicle. Optionally, the three zones have a common shell and are in direct or indirect flow communication with each other.

According to the invention, the occupant protection device has a second airbag system for protecting an occupant on a seat of the rear seat row, wherein the first airbag system and the second airbag system can be controlled and / or arranged independently of one another.

Each airbag system preferably has at least one independently operable gas generator, which can be activated separately and / or delayed in the event of an impact, depending on the need for impact protection. Thus, an airbag system can remain inactive in an impact, d. H. it does not necessarily have to be triggered if the other airbag system has already been triggered. In particular, the airbags of the first and second airbag systems are not in fluid communication with one another.

Conventional side impact protection devices in vehicles, especially in limousines, often comprise a so-called curtain airbag, which usually extends over both side windows of a vehicle side and is designed to protect a head region of the occupants on the front or rear seats.

Although these systems provide comprehensive protection due to their design and integration into a side roof area of the vehicle, they are expensive and are therefore often offered only as optional equipment in the vehicle. For this reason, not all vehicles are equipped with the curtain airbags, with the result that the head area of the occupants in many vehicles remains unprotected.

In addition, conventional curtain airbags usually have a high weight, which leads in the integrated state to increased energy consumption and increased CO emissions of the vehicle. Furthermore, the curtain airbag can only be activated as a whole on a vehicle side that extends along the entire area of the front and rear seats. This entails a considerable amount of repair work after triggering, which in turn leads to increased costs.

An advantage of the independent controllability and / or arrangeability of the two airbag systems is that, especially in comparison with the conventional curtain airbags, the repair costs can be reduced considerably after a release of only one of the two airbag systems. Alternatively and / or additionally, the independent arrangeability in many installation situations simplifies the integration into the vehicle and / or significantly reduces the installation costs.

In a preferred embodiment, the first airbag system is arranged in a seat of the first row of seats and / or the second airbag system in the seat of the rear seat row. In particular, the first and the second airbag system are arranged laterally in the backrest of the seat of the corresponding row of seats.

Optionally, the first and / or the second airbag system in a vehicle side, such. B. under a door trim in the area of the corresponding row of seats, be arranged. It is also conceivable that one of the two airbag systems in the seat of the corresponding row of seats, in particular in a backrest, is arranged, and the other of the two airbag systems in the vehicle side, in particular under the door trim.

In one possible embodiment, the second airbag system is designed as a three-zone airbag having a first zone, a second zone and a third zone, the first zone for protecting the pelvis, the second zone for protecting the thorax and the third zone for Protection of the occupant's head is formed.

As from the already mentioned prior art of the document DE 10 2005 050 935 A1 is known, side airbag systems that have an air bag to protect the head and / or the upper body and / or the pelvic region, previously installed only in the front seats. As a result, inmates in the rear seats are not or only insufficiently protected.

An advantage of the integration of the second airbag system in the area of the rear seat row is therefore that the three-zone airbag can also provide comprehensive protection for the occupants of the rear seat row for the body areas (head, upper body, pelvis) which are often the most vulnerable in a side impact , Furthermore, it is advantageous that it is possible to dispense with the conventional curtain airbag in the region of the rear row of seats. Thus, at the same time the associated disadvantages, such as high costs and heavy weight can be avoided.

In a preferred embodiment, the first and the second airbag system are of identical design and / or identical. As an advantage of the identical and / or identical design of the two airbag systems, a lesser development effort and lower integration costs can be mentioned. The two airbag systems make it possible to be arranged and / or installed in the same manner and in the same manner in the same design and / or identical training.

Another possible embodiment of the invention provides that the head zone in the activated state has a greater transverse extent in and / or counter to a direction of travel of the vehicle, as the first and / or the second zone.

In particular, the filled head zone is formed in a side view along a possible head movement path of the occupant. Preferably, the head zone is elliptical or circular in a side view. Optionally, it covers a wide area in the vicinity of the occupant's head and thus provides adequate protection even when the occupant has different seating positions.

In one possible embodiment, the head zone can cover with its extent and / or with its transverse extension in and / or against the direction of travel different sizes and / or postures and / or sitting positions of occupants.

A possible embodiment of the invention provides that the head zone is designed in a side view of a narrow side and / or top view from above wave-shaped. Thus, it is preferably reduced in thickness at regular or irregular intervals, in particular, the head zone has thicker and narrower protection areas. Optionally, the head zone provides several small-area support and / or abutment areas for the occupant. In particular, the head zone is at less than 70%, in particular less than 50% of the total surface extension of the head zone on the vehicle wall or are more than 30%, preferably more than 50% of the total areal extent set against a support surface to the vehicle wall of the head zone ,

An advantage of the wave-shaped design of the head zone is that it can be more easily deployed in narrow protective areas of the vehicle, since it has less volume. The volume reduction leads to a reduction in the weight of the first airbag system, which in particular can lead to cost savings. Furthermore, it is advantageous that the wave-shaped configuration can lead to a reduction of the friction during an expansion process.

In a possible development, the head zone is bowl-shaped, in particular it is formed bead-shaped in the direction of a head to be protected. Preferably, an edge region of the head zone forms a circumferential elevation, which may be interrupted in a neck and / or shoulder region of the occupant and / or formed with recesses. The edge region occupies a width of at least 2 cm, preferably at least 4 cm and up to 5 cm, preferably up to 15 cm, in particular up to 25 cm.

The bowl-like design, in particular the bead-shaped formation, can ensure an improved holding function of the head within a protective area and at the same time prevent the head from sliding out of the protected area. It is possible to significantly reduce the risk of injury by a possibility of contact of the occupant with areas of the vehicle side, such. B. a body pillar or a door frame, is significantly reduced. Particularly advantageous may be the bowl-like design of the head chamber in a frontal crash with a high lateral component and / or an angular crash prove. In such an impact, the occupant protection device according to the invention is triggered in addition to optionally provided Frontalairbagsystemen. Thus, in turn, a greater protective effect can be achieved.

In a further possible embodiment, the three-zone airbag in the filled state has a shape which, in a side view, resembles and / or resembles a contour of the occupant. This ensures sufficient protection for the three body regions pelvis, thorax and head, which are exposed to a high risk of injury in the event of an impact.

Preferably, the three-zone airbag in the region of the pelvis zone and / or the thorax zone in the direction of a vehicle roof has a greater longitudinal extent than the head zone.

In a particularly preferred embodiment, the transverse extent of the three-zone airbag decreases in the side view in and / or counter to the direction of travel of the vehicle from the head zone to the pelvis zone continuously from. In particular, the three-zone airbag is fan-shaped and / or shell-like and / or hammer-like and / or kidney-shaped and / or mushroom-shaped and / or blade-like and / or spade-like. Optionally, the head zone may have a larger volume than the thoracic and / or pelvis zones.

It is advantageous that an equally sufficient protective effect can be ensured for large and / or small occupants, since the three-zone airbag even in occupants with small body size has sufficient extension of the head zone. Furthermore, a satisfactory protective effect can be achieved even when the occupant leaves his normal sitting position.

A further development according to the invention provides that the thorax zone has a constant or almost constant has constant thickness. Optionally, the thoracic zone has a minimum thickness, which is based on a maximum energy input to be absorbed, which can be determined in calculations and / or tests. In particular, the minimum thickness is achieved by suturing, weaving, stitching and / or other measures in the same direction.

In a further possible embodiment of the invention, the second airbag system is designed as a two-zone airbag having a first and a second zone. The first zone is designed to protect the thorax (thorax zone) and the second zone to protect the head (head zone) of the occupant, especially the occupant in the back seat. Preferably, the thorax zone and the head zone are in direct flow communication with each other and are surrounded by a common shell, which delimits the two-zone airbag towards the vehicle.

The two-zone airbag differs from the three-zone airbag in the absence of the pelvis zone, which is designed to provide protection to the occupant's pelvis. However, the two-zone airbag may have the same characteristics and characteristics as the three-zone airbag in the region of the head zone and the thorax zone. In particular, the two zones assume the same functions as in the case of the three-zone airbag and / or are designed accordingly.

A conceivable configuration is also that the second airbag system comprises a combined airbag system which has a plurality of airbag modules, preferably two airbag modules.

In particular, each of the airbag modules comprises a separate shell, which delimits the airbag modules with each other and to the outside, ie towards the vehicle. Each of the airbag modules may have an associated gas generator. But it is also conceivable that all airbag modules only one gas generator is assigned, which can supply them via leads and / or valves and / or other same-way flow paths with gas.

In one possible embodiment, the combined airbag system comprises a pelvis / thorax airbag and a head airbag. The pelvis / thorax airbag is preferably designed for protecting the pelvis and / or the upper body and the head airbag for protecting the head of the occupant. The pelvis / thorax airbag is preferably arranged in the seat of the second row of seats, in particular laterally in the backrest of the seat. It is also conceivable that the pelvis / thorax airbag in the vehicle side, z. B. under the door panel, is arranged.

In particular, the head airbag is arranged in the vehicle side, wherein it is adapted to deploy in the direction of a vehicle roof. Thus, the head airbag can be arranged below a window under the door trim and expand after being triggered upwards, for example by rolling off the window.

In a further possible embodiment, the occupant protection device has an airbag system, which is designed as the second airbag system according to the following description and / or claims 10 to 15.

Another object of the invention relates to an airbag system, which is preferably designed as the second airbag system. The airbag system comprises a pelvis / thorax airbag and a head airbag, wherein the head airbag is arranged only in a protective area of the rear seat row and is adapted to deploy in the direction of a vehicle floor.

Preferably, the pelvis / thorax airbag is arranged in the vehicle side or in the seat of the rear seat row. For example, it may be installed under the door trim or laterally in the backrest of the seat. A further possible embodiment provides that the head airbag is designed to develop rectified to a vertical in the direction of a vehicle floor or at an angle to the vertical of up to 25 degrees, preferably of up to 50 degrees, in particular of up to 75 degrees ,

In particular, the head airbag expands after its release down. The head airbag in the activated state, the side window of the rear row of seats partially, preferably up to half, almost completely or completely cover. Preferably, the head airbag is sized sufficiently large to cover different sizes and / or postures and / or seating positions of the occupant and to provide a corresponding protective effect. Optionally, the head airbag can be rectangular or elliptical in a side view.

In a preferred embodiment, the head airbag is arranged in a roof frame of the vehicle, for example above the side window of the rear seat row.

Furthermore, it is possible that the head airbag is arranged in a C-pillar of the vehicle. The C-pillar includes the body pillar which separates the side window of the rearmost row of seats from the rear window of the vehicle.

Another object of the invention relates to a vehicle with the occupant protection device according to the previous description and / or the previous claims.
