Embodiment Construction

[0037] figure 1 The airbag 10 is shown in an unstitched state, which can be used as a knee airbag. The airbag 10 is a component of a vehicle occupant restraint system in a motor vehicle with which the vehicle occupants are protected. The airbag 10 generally forms an airbag module together with a gas generator (not shown here).

[0038]Since the airbag 10 is shown in the unsewn state, a blank 12 is shown corresponding to the airbag 10 , which in the embodiment shown comprises two cover sections 14 , 16 which are passed through Separately constructed housing parts 18 , 20 are formed.

[0039] In the embodiment shown, the first cover section 14 forms the rear side 22 of the airbag 10 in the inflated state. Furthermore, the first shell section 14 partially forms the front side 24 of the airbag 10 in the inflated state. The first cover section 14 thus has a rear side 26 forming the first region 28 of the blank 12 and a partial front side 30 which together with the second cover ...

Abstract

The invention relates to an airbag (10) for a vehicle occupant restraint system, the airbag (10) when inflated having a front side (24), forming an occupant impact surface, and an opposite rear side (22). The front side (24) and the rear side (22) are formed by outer surface portions (14, 16) of the airbag (10), which are connected to one another at their outer edges (34, 36). The front side (24)is longer than the rear side (22) along a centre line (M) which runs in the longitudinal direction of the airbag (10), and therefore the airbag (10) when inflated has a curved shape. The front side (24) has at least one substantially curved shaping line (42) running transverse to the centre line (M), with two outer surface portions (14, 16) being connected to one another at said shaping line. Theouter edges (34, 36) of the front side (24) and the outer edges (34, 36) of the rear side (22) have the same overall length respectively.

Description

technical field [0001] The invention relates to an airbag, in particular a so-called knee airbag, for a vehicle occupant restraint system. Background technique [0002] Airbags for use in motor vehicles to protect vehicle occupants, for example in the knee region, are known from the prior art. Such airbags are also referred to as knee airbags. In the case of knee airbags, a distinction is usually made between two different designs in which the airbag is arranged in a visible area or in an invisible area within the motor vehicle. In the case of knee airbags arranged in the visible area, for example, a view shield is provided, which is usually arranged under the steering column guard on the driver's side or below the glove box on the passenger side . A knee airbag arranged in a non-visible area is arranged, for example, under the instrument panel or behind it. [0003] In the case of knee airbags or corresponding airbag modules which are arranged in the non-visible region,...
