Problems solved by technology

[0005] However, when the inflated part of the air seat belt is inflated, the internal pressure is uniformly generated in the inflated part, so the cross-sectional shape of the inflated part tends to become circular in general.
Therefore, as described in the above-mentioned Patent Document 1, if the inflated portion is made la

Embodiment Construction

[0025] Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1 , the vehicle air safety belt device 10 of the present embodiment is a seat belt for constraining an occupant 14 sitting on a vehicle seat 12, including a webbing 16 for occupant restraint, an inflatable portion 18, a An inflator (not shown) that supplies gas to the inflation portion 18, a sensor (not shown) that detects or predicts a side impact, and a control unit (not shown) that operates the inflator based on an output signal from the side impact sensor ), seat belt guide 20.

[0026] The vehicle seat 12 is, for example, a bucket seat in which the headrest portion 28 is integrally provided on the seat back 26. The headrest portion 28 and the seat back 26 are integrally provided with, for example, a slope extending in the shape of a mountain when viewed from the front of the vehicle. Sections 22, 24. The seat belt guide 20 is provided, for example, on...

Abstract

The invention provides an air belt device for a vehicle capable of improving occupant restraining performance by expanding an expansion part larger in the vehicle vertical direction at a position opposed to a head part of an occupant in the vehicle widthwise direction and absorbing inertial force in the vehicle widthwise direction of the head part by the expansion part in side surface collision while securing usability of a webbing for occupant restraint in normal use. A belt guide 20 provided on an inclined part 22 (shoulder part) of a seat back 26 on a seat 12 for the vehicle can deploy in a direction separated from the head part 14H up to a specified angle to be limited by stopper parts 40S, 42S around a fulcrum 36 positioned on the outside in the vehicle widthwise direction as its center from a normal state to guide the webbing 16 for occupant restraint when the expansion part 18 expands. Consequently, it is possible to expand the expansion part 18 to an upward position opposed to the head part 14H in the vehicle widthwise direction by regulating an expanding shape of the expansion part 18.

Description

technical field [0001] The present invention relates to an air safety belt device for a vehicle having an inflation portion corresponding to the head of an occupant when inflated. Background technique [0002] Patent Document 1 discloses an air safety belt device equipped with a height position control unit that generally sets a shoulder anchor for guiding an occupant restraint webbing provided with an inflated portion at a different position. At the height position facing the side of the occupant's head, the shoulder anchor is set at a position facing the side of the occupant's head during a side collision (see Patent Document 1). On the other hand, Patent Document 2 discloses an air belt device in which a belt guide for guiding an occupant restraining webbing is fixed to a seat back shoulder (see Patent Document 2). [0003] Patent Document 1: JP-A-2001-239906 [0004] Patent Document 2: JP-A-2002-527282 [0005] However, when the inflated portion of the air belt is inf...
