Embodiment Construction

[0044] Embodiments of the present invention will be described below using the drawings. An airbag device (occupant protection device) 10 according to an embodiment of the present invention is accommodated in a center pad 7 of a steering wheel 3 . Furthermore, the airbag device 10 has a head protection air bag body (first air bag body) 11 and a chest protection air bag body (second air bag body) 12 that can be deployed toward the occupant side at the time of a vehicle collision. And constitute.

[0045] In addition, as described above, the airbag device 10 of the present embodiment is constituted by having the head protection airbag body 11 for head protection and the chest protection airbag body 12 for chest protection, but is not limited thereto. For example, a pressure valve or the like may be used to form a plurality of chambers in one airbag body.

[0046] First, for the steering wheel 3 of the vehicle 1 to which the airbag device 10 according to one embodiment of the pr...

Abstract

There is provided an occupant protection device. Via more effective protection of an occupant from vehicle impact, safety of protecting the occupant from vehicle impact can be improved. An air bag device (10) according to the present invention protects an occupant against an impact caused by a collision of a vehicle (1) by inflating and expanding a head protection air bag body (11) and a chest protection air bag body (12) upon the impact which are housed in a center pad (7) of a steering wheel (3), the occupant protection device (10) including an inflation and expansion mode control unit (15) configured to inflate and expand the head protection air bag body (11) and the chest protection air bag body (12) mutually independently in accordance with a collision mode of the vehicle (1), and to control inflation and expansion modes of the head protection air bag body (11) and the chest protection air bag body (12) when inflated and expanded.

Description

technical field [0001] The present invention relates to an occupant protection device, and in particular, relates to an occupant protection device configured by accommodating an airbag bag body in a center pad of a steering wheel (sterling). Background technique [0002] Currently, it is known that an airbag body is folded and housed in a center pad of a steering wheel as an occupant protection device, and when a vehicle collides, the airbag body is deployed toward the occupant side to protect the occupant from impact. [0003] Here, generally, the center pad of the steering wheel rotates together with the steering wheel in accordance with the driving operation of the occupant. Therefore, the airbag body accommodated in the center pad can be inflated and deployed in the same shape and formed in a circular shape regardless of the steering angle of the steering wheel. Also, the airbag body formed in a circular shape mainly protects the occupant's head. [0004] In recent yea...
