Embodiment Construction

[0031] figure 1 An airbag housing 1 for accommodating a cylindrical gas generator (not shown) and an airbag package 2 are shown. The airbag package 2 consists of a folded airbag 3 which is connected to a support frame 4 in the region of a nozzle (not shown) ( figure 2 ) and is surrounded by the protective cover 2a. In a first step a, the airbag package 2 is inserted into the airbag housing through the opening 5 in the airbag housing. In a second step b, the support frame 4 and the airbag package 2 are thus secured in the airbag housing 1 by means of separate locking clips 6 which engage through through openings 7 in the airbag housing 1 . Specifically as figure 2 As shown in , the latching clamp 6 has a clamping portion 8 and latching portions 9 and 10 . Adjoining the closure part 10 is a closure part 11 on the airbag housing 1 , the airbag housing 1 having an opening 12 in the region of the closure part 11 . The latching portion 9 has a hole 9 a which engages with a pr...

Abstract

The invention relates to a device for fixing an airbag fastened to a support frame in a housing of a front passenger airbag module by means of at least one clamping element. In order to fix the support frame of the airbag in the airbag housing so that the installation costs are low and if the airbag is installed in a soft protective cover when the airbag is folded, damage to the protective cover during the installation of the airbag is at least Very adequately prevent that, according to the invention, the housing (1, 16) and the clamping element (6, 14) are non-deformable in the region of the support frame (4), the clamping element (6, 14 ) is not connected by screws or rivets and is dimensioned in such a way that when it is in the clamped position it is spaced from the support frame (4) by a distance greater than any provided for the airbag (3) The thickness of the protective film (2a) and the clamping element (6, 14) is fixed in its clamping position by means (9a, 10, 11, 13a) having a certain distance from the support frame (4).

Description

technical field [0001] The invention relates to a device for securing an airbag fastened to a support frame in a housing of a front passenger airbag module. Background technique [0002] Various methods are known for securing an airbag fastened to a support frame within the housing of the airbag module. For example, DE 19850463 A1 discloses an airbag assembly in which the airbag is connected to a support frame with locking elements by means of which the support frame and thus the airbag can be secured in the housing. Because of this locking element, the airbag module has the disadvantage that it becomes more difficult to weld the folded airbag into the soft cover enclosing the airbag package in a gas-tight manner. The airtight package makes it possible to minimize the size of the airbag package by creating a low pressure in the soft boot. A further disadvantage is that the housing must have a double-walled design in the locking region. [0003] In the airbag assembly disc...
