Description

The invention relates to a vehicle occupant restraint system for a motor vehicle and to a motor vehicle with a vehicle occupant restraint system.

Vehicle occupant restraint systems are set up to support vehicle occupants if necessary. Depending on the type of requirement, different restraint systems can be activated. There is a constant effort to optimize the vehicle occupant restraint systems in order to protect vehicle occupants even better if necessary.

It is therefore an object of the invention to provide an improved vehicle occupant restraint system.

This object is achieved according to the invention by a vehicle occupant restraint system for a motor vehicle with a vehicle seat and a seat-integrated gas bag, on which at least one tension strap is provided, which in an inflated state of the gas bag over an outside of the gas bag facing away from the vehicle seat and / or along a circumferential edge of the gas bag, the tension band being fixed with at least one end to the vehicle seat and the tension band being held in at least one holding point on the gas bag. In a preferred embodiment, both ends of the tension band are mounted on the vehicle seat directly or indirectly, for example via the gas bag module comprising the gas bag.

Such a vehicle occupant restraint system has the advantage that the gas bag is held particularly reliably in a position by the drawstring when necessary in which it can support a vehicle occupant. The gas bag does not have to be supported on a vehicle structure, as a result of which the geometry and position of the gas bag can be selected in a particularly flexible manner. In particular, the vehicle occupant restraint system according to the invention prevents transverse displacements of the vehicle occupants.

In the inflated state of the gas bag, the tension strap can in particular bring about a tensioning force in the gas bag which acts in a plane which runs transversely to a displacement of a vehicle occupant if necessary. As a result of this tensioning force, the gas bag can have a higher rigidity in the inflated state and produce an improved restraint force on a vehicle occupant, since movement of the gas bag can be kept small.

If, for example, only one driver is present in the front area of the vehicle and the front passenger seat is unoccupied, the driver can be supported on the driver's seat by means of the gas bag. If the driver is pressed against the gas bag due to centrifugal forces, the tension band acts on the gas bag with a counterforce which supports the gas bag against the movement of the driver and thus also supports the driver laterally. Such a need can occur in a so-called Farside collision, that is, when a collision occurs on a vehicle opposite the driver's side. If a passenger is also present in addition to the driver, the gas bag can, if necessary, also prevent the driver and passenger from colliding, in particular with their heads.

According to one embodiment, in the inflated state of the gas bag, the holding point lies in a side view on the circumferential edge of the gas bag. The side view relates to a mounted state of the gas bag in the vehicle. Such an arrangement of the holding point allows the gas bag to be kept particularly stable. In particular, a movement of the gas bag in its holding position is avoided.

The holding point is preferably located on an outer edge of the gas bag that is remote from a backrest of the vehicle seat, that is to say, viewed in the longitudinal direction of the vehicle, on a front side of the gas bag when it is arranged in the vehicle and inflated. As a result, a lever arm of the tension band is maximized, as a result of which the tension band can bring about a particularly large retaining force on the gas bag.

The at least one holding point can be formed by a cutout through which the tension band runs. The drawstring can thus be coupled to the gas bag in a particularly simple manner in that it is passed through the recess, that is to say is threaded into the recess.

For example, on the outside of the gas bag facing away from the vehicle seat, at least one additional fabric layer is provided, the tension band running at least in sections between the additional fabric layer and the outside of the gas bag. The fabric layer thus preferably forms a guide channel in which the tension band runs. In this case in particular, the inlet and outlet openings of the guide channel form the recesses. The provision of an additional fabric layer has the advantage that a holding point can be flexibly positioned on the outside of the gas bag. In addition, a stop point can be expanded to a stop line by means of a fabric layer. This improves the guidance of the tension band along the outside of the gas bag.

The recess can be arranged outside an inflatable area of the gas bag, in particular on a circumferential collar of the gas bag. A collar is a layer of fabric that lies outside a seam that delimits the inflatable area. Recesses can therefore be provided in the collar without any problems without increased gas being able to escape from the gas bag. In the collar, recesses for holding the tension band can thus be formed in a particularly simple manner, for example by cutting holes in the collar. The recesses can optionally be reinforced, for example with perforated rivets.

According to a further embodiment, the recess is a hole in an additional piece of fabric attached, in particular sewn, to the airbag.

According to one embodiment, the gas bag can have a head chamber and a torso chamber adjoining the head chamber, the tension band being held on the torso chamber and in particular running along an outside of the torso chamber. The head chamber and torso chamber are preferably attached to one another in a connecting area. A vehicle occupant can be particularly well supported by means of such a gas bag. In particular, the gas bag is adapted in this way to a body shape of the vehicle occupant. This means that the head chamber specifically supports the head and the torso chamber specifically supports the torso of a vehicle occupant by, for example, the head chamber protruding towards the vehicle occupant over the torso chamber and thus bridging the distance between a shoulder and the head of the vehicle occupant.

For example, at least two holding points are provided on the gas bag, which are arranged on opposite edge sections of the gas bag when the gas bag is inflated, in particular with one holding point being arranged on a front edge and one holding point, based on the vehicle direction, on a rear edge of the gas bag. As a result, the tension strap can be held particularly reliably in a desired position on the outside of the gas bag when the gas bag is inflated and in the inflated state of the gas bag. In particular, it is avoided that the drawstring slips, even if high forces act in the drawstring when supporting a vehicle occupant.

For example, the drawstring runs across the outside of the gas bag facing away from the vehicle seat, in particular the torso chamber, if two holding points are provided.

For example, at least one further holding point is provided, which is also arranged on a front edge of the gas bag when the gas bag is inflated. As a result, the gas bag can be held in an even more stable manner than with two holding points. In addition, a course of the tension band can be specified more specifically.

The airbag is preferably a central airbag which is installed in the vehicle seat on a side facing another vehicle seat. In other words, the gas bag can be inflated between two places for vehicle occupants that are adjacent transversely to the direction of travel. The gas bag can thereby support both a driver and a passenger to a certain extent and prevent a collision between the two vehicle occupants.

According to one embodiment, the tension band of the gas bag is fixed with its end on a frame of a seat surface of the vehicle seat. The frame of the seat is particularly stable and is therefore suitable for absorbing the forces transmitted from the tension band to the frame when necessary. The attachment is provided in particular on the side of the vehicle seat.

The tension band can be fastened at both ends to the vehicle seat, in particular the tension band being fastened in the area of a backrest of the vehicle seat and in the area of a seat surface of the vehicle seat. As a result, the tension strap can be stretched on the side of the vehicle seat when the gas bag is in the inflated state. If the tension band is fastened in the area of a backrest of the vehicle seat and in the area of a seat surface of the vehicle seat, the tension band can in particular be stretched transversely between the backrest and the seat surface. In this way, the gas bag can be supported laterally in a particularly reliable manner.

The vehicle seat has, for example, a base frame, one end of which is attached to the foremost point of the base frame in relation to the vehicle direction. In this way, a span of the tension band can be at a maximum, as a result of which the gas bag can be stabilized particularly reliably by the tension band.

For example, the gas bag is arranged on a side of the vehicle seat directed towards a center console when the vehicle seat is mounted in a motor vehicle. As a result, the gas bag can support both a driver and a passenger.

The object is also achieved by a motor vehicle with a vehicle occupant Restraint system, which is designed as described above.

• 2a and 2 B show partially schematically a vehicle occupant restraint system according to the invention 12 with a vehicle seat 14th and a gas bag 16 which can be inflated if necessary. The fastening of the gas bag is here for better illustration 16 just a basic frame 18th of the vehicle seat 14th shown. A complete vehicle seat 14th including trim and upholstery parts is for example in 3 shown.

The gas bag 16 is in the 2a and 2 B shown schematically, where in 2a the gas bag 16 in a deflated state and in 2 B is illustrated in an inflated condition. In 2 B is in particular a circumferential edge 25th of the gas bag 16 shown in the inflated state.

Inflating the gas bag 16 takes place if necessary by means of a gas generator 20th on the side of the vehicle seat 14th is attached.

With the gas bag 16 it is a seat-integrated gas bag 16 . More precisely, is the gas bag 16 a central airbag in the vehicle seat 14th one to another vehicle seat 14th facing side is installed.

When the vehicle seat 14th in the motor vehicle 10 is mounted, is the gas bag 16 on a side of the vehicle seat directed towards a center console 14th arranged.

On the gas bag 16 is at least one drawstring 22nd intended. In the 2a and 2 B illustrated embodiment, this runs in the inflated state of the gas bag 16 over one of the vehicle seat 14th facing away from the outside 24 of the gas bag 16 , as in 2 B to see is. The course of the tension cord 22nd to a desired shape of the gas bag 16 be adjusted when inflated, that is, the drawstring 22nd can arcuate along the outside 24 of the gas bag 16 run away.

In other words, the drawstring serves 22nd also for shaping the gas bag 16 .

The drawstring 22nd is in two breakpoints 26th on the gas bag 16 held. The breakpoints 26th lie on the surrounding edge 25th of the gas bag 16 . In the inflated state of the gas bag 16 are the breakpoints 26th on opposite edge sections of the gas bag 16 arranged. In particular is a breakpoint 26th based on the direction of the vehicle at a leading edge 17th and a breakpoint 26th on a trailing edge 19th of the gas bag 16 arranged.

The ends 28a , 28b of the drawstring 22nd are at the vehicle seat 14th fixed, in particular on the base frame 18th of the vehicle seat 14th . More precisely, there is an end 28a of the drawstring 22nd in a fastening point 29a on the frame 30th a seat 32 of the vehicle seat 14th attached, in particular at a foremost point of the base frame in relation to the vehicle direction 18th .

The further end 28b of the drawstring 22nd is in a fastening point 29b in the area of a backrest 34 of the vehicle seat 14th attached. For example, the further end 28b also on the gas generator 20th be attached.

Between the two attachment points 29a , 29b of the drawstring 22nd this runs continuously, i.e. without interruptions. In particular is the drawstring 22nd one piece.

When the gas bag 16 is inflated, the drawstring can 22nd on the gas bag 16 exert a holding force and the airbag 16 hold in a holding position in which the airbag 16 can support a vehicle occupant, in particular a driver, particularly well.

The drawstring does this 22nd a tension in the gas bag 16 that helps the gas bag 16 to hold in a holding position. The clamping force is for example in 2 B illustrated by an arrow.

The clamping force acts in particular in a plane which runs transversely to a displacement of a vehicle occupant if necessary, in particular in the event of a side impact. As a result, a vehicle occupant can be particularly reliably supported when shifting transversely to the vehicle longitudinal direction.

The breakpoints 26th are thereby through recesses 36 formed by which the drawstring 22nd runs. The recesses 36 are indicated in the figures by circles.

The recesses 36 can be in additional fabric layers 37 be formed in 2 B are illustrated. The additional layers of fabric 37 are for example with the gas bag 16 along the circumferential edge 25th sewn.

However, it is also conceivable on the gas bag 16 a fabric overhang, in particular a circumferential collar outside an inflatable area of the gas bag 16 provide in which the recesses 36 can be formed.

4th illustrates partially schematically a further embodiment of a vehicle occupant restraint system according to the invention 12 . In contrast to the 2a , 2 B and 3 The embodiment shown has the gas bag 16 a head chamber 38 and one to the head chamber 38 subsequent torso chamber 40 . The head chamber 38 extends in the direction of the vehicle seat 14th or to a driver via the torso chamber 40 out when the gas bag 16 is in the inflated state. In this way, the gas bag 16 be adapted to a body shape of a vehicle occupant. In addition, a vehicle occupant can be protected particularly reliably against a collision with structural vehicle components.

The drawstring 22nd is at the torso chamber 40 held and runs in particular along an outside 24 the torso chamber 40 .

The 5 and 6th show a vehicle occupant restraint system 12 according to 4th with a head chamber 38 and a torso chamber 40 , in which 5 the vehicle occupant restraint system 12 in a side view and 6th the vehicle occupant restraint system 12 shows in a front view.

In 5 is the arched course of the drawstring 22nd to recognize.

As in 6th can be seen is between the head chamber 38 and the torso chamber 40 an additional layer of fabric 41 available. Through the fabric layer 41 can in particular the positioning and the location of the head chamber 38 opposite the torso chamber 40 be stabilized. Furthermore, the fabric layer 41 help to ensure that a forward movement (based on a vehicle longitudinal direction) of the vehicle occupant along the gas bag 16 can be limited, especially in the event of an oblique frontal impact or a Farside impact, in which movement of the Vehicle occupants are caused to the side and forward.

As well in 5 as well as in 6th are those in the gas bag 16 acting clamping forces illustrated by arrows. In 6th is also one when the vehicle occupant is displaced against the gas bag 16 illustrated supporting force acting on this.

7th Figure 3 shows a vehicle occupant restraint system 12 according to a further embodiment.

The embodiment according to 7th is similar to the embodiment according to FIGS 2a and 2 B , with the difference that three instead of only two breakpoints 26th are provided. This means that the course of the tension band is different 22nd in the inflated state of the gas bag 16 compared to that in the 2a and 2 B illustrated embodiment. In particular, the drawstring runs 22nd in sections along the circumferential edge 25th of the gas bag 16 and in sections over an outside 24 of the gas bag 16 .

The one by the drawstring 22nd In this case, too, the tension force caused acts between the fastening points 29a , 29b .

The in 7th shown gas bag 16 can optionally also have a head chamber 38 and a torso chamber 40 exhibit. The drawstring 22nd then runs at least in sections at a transition between the head chamber 38 and the torso chamber 40 .

A vehicle occupant restraint system 12 with such a gas bag 16 is in the 8th and 9 illustrates where 8th a side view and 9 Fig. 3 is a front view of the vehicle occupant restraint system 12 represents. The shape of the gas bag 16 corresponds to that in the 5 and 6th shown gas bag 16 only the course of the drawstring 22nd is due to the different number of breakpoints 26th different.

The 10 and 11 each show a further embodiment of a vehicle occupant restraint system 12 with an alternative arrangement of the breakpoints 26th .

At the in 10 illustrated embodiment is a breakpoint 26th in the inflated state of the gas bag 16 at a transition from a lower edge of the gas bag 16 to a front edge of the gas bag 16 arranged.

The two ends 28a , 28b of the drawstring 22nd are in this embodiment on the frame 30th the seat 32 of the vehicle seat 14th attached.

In the 11 The embodiment shown differs from that in FIG 10 embodiment shown in that a further breakpoint 26th is provided in the inflated state of the gas bag 16 at the transition from a lower edge 21st of the gas bag 16 to a trailing edge 19th of the gas bag 16 is arranged.

The ends 28a , 28b of the drawstring 22nd are on the frame 30th the seat 32 and in the area of the backrest 34 attached. In particular, there is an end 28b of the drawstring 22nd at the transition from the frame 30th the seat 21st to the backrest 34 arranged.

In the 10 and 11 The illustrated embodiment runs the drawstring 22nd along the surrounding edge 25th of the gas bag 16 especially along the bottom edge 21st .

12 Figure 3 shows another embodiment of a vehicle occupant restraint system 12 . In this embodiment are on the outside facing away from the vehicle seat 24 of the gas bag 16 additional layers of fabric 42 provided, the drawstring 22nd in sections between the additional fabric layers 42 and the outside 24 of the gas bag 16 runs. Through the layers of fabric 42 a guide channel is thus formed in which the tension band 22nd runs.

Based on 13 to 16 The following are the advantages of a vehicle occupant restraint system according to the invention 12 clarified.

13 and 14th illustrate the operation of a conventional vehicle occupant restraint system. The gas bag 16 is in this case by means of a fastening 44 only on one side of the vehicle seat 14th fixes what's in the 13 and 14th is illustrated schematically. For the sake of simplicity, it is assumed that the airbag 16 when a vehicle occupant is supported on the outside facing the vehicle occupant, a force is applied uniformly, which is shown in FIG 13 is illustrated by means of arrows.

q ist dabei die Flächenkraft und I die Länge des Gassacks 16 in Fahrzeuglängsrichtung.A moment M ₁ acts on the gas bag, which is calculated as follows: $${\mathrm{M.}}_1=\frac{q\ast l^2}{2}$$

q is the surface force and I the length of the airbag 16 in the longitudinal direction of the vehicle.

The gas bag bends due to the moment M ₁ 16 to the side, as in 14th you can see. For better illustration, there is a bend in the gas bag 16 in 14th indicated by a curved line.

The dashed line in 14th illustrates the maximum displacement of the vehicle occupant in the lateral direction.

The 15th and 16 illustrate a vehicle occupant restraint system according to the invention 12 , with the gas bag 16 if necessary by means of the drawstring 22nd between two attachment points 29a , 29b is kept under tension.

As in 16 is illustrated by the curved line, the gas bag can 16 in this case bend, but it does not bend forward. This limits a lateral displacement of the vehicle occupant, which is shown in FIG 16 is illustrated by a dotted line. For a better comparison, in 16 the displacement of the vehicle occupant in a vehicle with a conventional vehicle occupant restraint system is shown using a dashed line.

The resulting, on the gas bag 16 of the vehicle occupant restraint system according to the invention 12 Acting moment M _{2 is} calculated as follows: $${\mathrm{M.}}_2=\frac{q\ast l^2}{12}$$

This means that the resulting moment M ₂ that acts on the airbag 16 in the vehicle occupant restraint system according to the invention 12 is significantly smaller than with a conventional vehicle occupant restraint system. In purely mathematical terms, the moment M _{2 is} only one sixth of the moment M ₁ . Due to the lower resulting torque, a displacement of a vehicle occupant can be kept low if necessary.
