Embodiment Construction

[0030] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0031] figure 1 is a perspective view showing a joint airbag module according to an embodiment of the present invention, Figures 2 to 5 are shown respectively figure 1 perspective, side, front and plan views of the cushion shown in its inflated state, Figure 6 is a side view showing the driver colliding with the mat.

[0032] Such as Figure 1-5 As shown, the combined airbag module A according to the present invention includes a cushion 2 , a fixing member 4 and an inflator 6 .

[0033] The cushion 2 is formed by binding the edges of the two fabrics after overlapping each other so that an inflatable space can be formed inside the cushion 2 . Preferably, the cushion 2 is inflated into a substantially C-shape viewed in plan so as to protect the front and sides of the occupant.

[0034] The cushion 2 is wound and arranged on the fix...

Abstract

Disclosed is a unification airbag module. The unification airbag module includes a cushion to protect a front and a side of an occupant, a fixing member mounted on a ceiling of a vehicle and formed therein with a capacity such that the cushion is rolled and received in the cavity, and an inflator supplying inflation gas to the cushion. The cushion includes a front portion corresponding to a head and a chest of the occupant, and a side portion corresponding to both sides of the head and the chest of the occupant. A main chamber is formed on edges of the front and side portions, and a plurality of sub-chambers communicating with the main chamber are formed at the front portion and the side portion. The occupant is completely surrounded by the unification airbag module so that the occupant is protected from the front collision and the side collision.

Description

technical field [0001] The present application relates to joint airbag modules. More specifically, the present application relates to a combined airbag module capable of functioning as a passenger airbag and a side curtain airbag by simultaneously protecting the front and sides of an occupant during airbag operation, and preventing the impact of the inflated airbag from being directly applied to the airbag by providing a shock absorbing unit. The occupant's face can thus be protected. Background technique [0002] In general, an airbag system is a representative safety device for protecting passengers when a vehicle collides. [0003] The airbag system is classified into driver airbag (DAB), passenger airbag (PAB) and side curtain airbag (CAB). Fitting on the side part of the vehicle makes it possible to ensure the safety of the occupants in the event of a side collision. [0004] Therefore, the driver airbag and the passenger airbag are operated to protect the occupant d...
