Embodiment Construction

[0029] exist figure 1 A vehicle seat 1 is disclosed in . The seat can be used, for example, as a driver's seat. The seat consists of three main parts, namely the backrest 2 , the seat cushion 3 and the headrest 4 . The backrest 2 includes a front side 2 a facing an occupant sitting in the vehicle seat 1 and a rear side facing away from the occupant sitting in the vehicle seat. The backrest also includes a first transverse portion 2c and a second transverse portion 2d , an upper portion 2e close to the headrest 4 and a lower portion 2f close to the seat cushion 3 . The seat cushion 3 comprises an upper side 3 a intended to contact and face an occupant seated in the vehicle seat 1 and a lower side 3 b facing away from the occupant. The seat cushion comprises a first transverse portion 3c, a second transverse portion 3d, a front portion 3e and a rear portion 3f close to the backrest 2. The headrest comprises a front side 4a intended to contact and face the head of an occupant...

Abstract

The invention relates to an air bag device (5) for a vehicle seat (1) and a vehicle seat (1) comprising such an air bag device (5). The airbag device (5) is designed to have a first air bag portion (5a) to be attached to at or close to a first lateral side (2c) of a backrest (2) and a second air bag portion (5b) to be attached to a second lateral side (2d) of a backrest (2). Furthermore, the firstair bag portion (5a) and second air bag portion (5b) are connected with each other by a third air bag portion (5c) designed to be located along a part of the upper portion (2e) of a backrest (2). Theair bag device (5) is designed to, when mounted to a vehicle seat (1), limit the lateral movement of the torso of an occupant and protect an occupant. The third portion (5c) will contribute with an increased stability of the air bag device (5) when deployed. In addition, the air bag device (5) may be designed to protect the head of an occupant from injuries.

Description

technical field [0001] The present invention relates to an airbag device and a vehicle seat provided with the airbag device. Airbag arrangements are intended in particular to protect passengers in the transverse direction relative to the vehicle seat in the event of an accident, such as a side impact. Background technique [0002] In order to prevent occupants in a vehicle seat, such as a driver's seat or a passenger seat, from being injured by lateral movement, vehicles have been provided with so-called inflatable curtains (IC). These ICs are typically mounted above the doors along the lateral sides of the vehicle. In an emergency, the inflatable curtain is deployed and injuries caused by a passenger's head or torso hitting the side of the vehicle are reduced. However, these ICs will only protect against lateral movement of the body towards one side, the passenger side near the outside of the vehicle. In the event that the occupants are subjected to forces acting in the ...
