Definitions
- the invention relates to an airbag for the protection of a passenger in a motor vehicle, in particular a rear passenger.
- an airbag in the back of a front seat would not be satisfactory. For example, it would be necessary to be able to compensate for the greater or lesser distance between the rear passenger and the backrest, a distance which varies according to the adjustment of the longitudinal position of the seat and of the adjustment of the inclination of the backrest.
- the implementation of an airbag requires the use of a number of components such as a gas generator, a pyrotechnic release device and a deceleration detector, components that are difficult to integrate into a structure such as that of a seat.
- the cushion Furthermore, it is necessary for the cushion to deploy while being as close as possible to the passenger so that he can play his protective role as quickly as possible.
- the object of the invention is to propose an airbag device for the protection of a rear passage of a motor vehicle, the installation of which is easy and allows the deployment of the cushion in the best possible conditions.
- the invention provides an airbag, characterized in that the airbag is stored in a housing arranged in a side panel of the vehicle, next to the passenger, and in that the airbag is intended to deploy in a direction slightly oblique to the transverse direction of the vehicle so as to deploy as close as possible to the passenger.
- the cushion is generally elongated in the direction of its direction of deployment, which is inclined about ten degrees backwards relative to the transverse direction of the vehicle;
- the cushion is designed to come between the head of the passenger and his lower limbs; - the cushion deploys by resting on the passenger's thighs;
- the cushion is intended to bear against a surface arranged in front of the passenger; - The cushion is intended to bear against the back of a front seat of the vehicle;
- the cushion is stored by being wound substantially around an axis of long itudinal orientation;
- the housing in which the cushion is stored is closed on the side of the passenger compartment of the vehicle by a trim lining which is provided with a tear primer to allow deployment of the cushion;
- the housing in which the cushion is stored is arranged in a side door;
- the cushion is substantially in the form of a cylinder with an axis parallel to its direction of deployment.
- FIG. 1 is a schematic perspective view illustrating an airbag according to the invention in the deployed position, before the passenger has been thrown forward under the effect of a frontal impact;
- Figure 2 is a top view of Figure 1;
- FIG. 3 is a schematic perspective view illustrating the relative position of the passenger, the airbag and the seats after the passenger has been thrown forward under the effect of the shock;
- FIG. 1 shows a passenger 10 who is installed in a rear seat 12 of a motor vehicle, that is to say behind a front seat 14.
- Passenger 10 is strapped to his rear seat 12 using a seat belt 16, preferably at three points, that is to say comprising a strand which extends across thorax and a strand which extends across the pelvis, and possibly provided with at least one force limiter.
- an airbag 18 is also provided, also called an airbag or “airbag”, which is intended to extend in front of the rear passenger 10 for prevent his chest and head from abruptly pressing against the front seat 14 or against his own lower limbs.
- the airbag 18 is a generally cylindrical cushion, of axis A1 substantially transverse, perpendicular to the direction of advancement of the vehicle, and it is intended to be deployed from a lateral body panel 20 of the vehicle in which it is stored as can be seen more particularly in FIG. 4.
- This side panel 20 can be either a door or a fixed panel.
- a support 28 for the airbag Inside the internal space 22 of the panel 20 is arranged a support 28 for the airbag.
- the circular edge of one end of the cylindrical cushion 18 is fixed to an internal face 30 of the support 28, for example by means of a flange 32.
- a gas generator 34 is arranged on the internal face 30 of the support 28, substantially in the center thereof, on the axis A1 of deployment of the airbag 18.
- the airbag 18 When the airbag 18 is in the storage position, it is folded between the support 28 and an internal face 36 of the interior lining 26. It can be folded in accordion or, preferably, wound in a spiral around a longitudinal axis substantially parallel to the longitudinal direction of advance of the vehicle.
- a device for detecting deceleration is capable of triggering a pyrotechnic device capable of using the gas generator 34 which then causes the airbag 20 to inflate.
- the swelling of the cushion 20 causes the inner lining 26 to be torn, which is moreover provided with a rupture initiator 40 arranged substantially along the axis A1 of deployment of the cushion 20 to facilitate this tearing.
- the cushion 18 deploys very quickly inside the passenger compartment of the vehicle, preferably before the passenger 10 has moved a significant amount under the effect of deceleration.
- the arrangement of the cushion 18 in the body panel 20 is chosen so that it deploys by resting on the thighs 38 of the passenger 10, as close as possible to the chest.
- the cushion 18, in the form of a cylinder of revolution is deployed not strictly perpendicular to the longitudinal direction of the vehicle, but along an axis A1 slightly inclined towards the rear, for example of about ten degrees. This ensures that the cushion 18 will be as close as possible to the chest of the passenger 10 despite the fact that the cushion 18, also subject to the effect of the sudden deceleration of the vehicle, tends to move forward.
- FIG. 3 shows the relative position of the passenger, the airbag 18 and the seats 12, 14 when the passenger 10 is thrown forward under the effect of the frontal impact.
- This figure also illustrates the tendency to "submarining" of the passenger whose pelvis tends to crush the seat 12.
- the thorax and the head of the passenger 10 being projected forward, they tend simultaneously to bend towards the low.
- the arrangement of the airbag 18 according to the invention makes it possible to prevent the passenger's head from hitting either his lower limbs, and in particular his knees, or the back of the front seat 14. The cushion 18 is then found interposed between the passenger's head 10, his knees, and the back 15 of the front seat 14 against which he rests to retain the passenger 10.
- the airbag 20 according to the invention may have a diameter of 600 mm and a length along its direction of deployment of 800 mm.
