[0008] However, in the occupant restraint device of this publication, the shoulder straps are as described in this publication. figure 1 As shown, since the thickness of the part from the head side to the front side of the occupant (hereinafter sometimes referred to as the front part) is roughly the same or the front part is thicker, it is filled from the beginning to the shoulder belt. It takes quite a while for the gas to reach a sufficiently high internal pressure in the head side arrangement

Abstract

In order to further speed up the inflation of the head-side portion of an occupant restraint belt that passes by the head of an occupant and routed across the front of the occupant, and which is inflatable from the head-side portion disposed on the side of the occupant's head across the front portion disposed at the front of the occupant, a shoulder belt section (10) of an occupant restraint belt (1) has a head-side portion (10S) located on the side of the head of an occupant; and a front portion (10F) located across the front of the occupant. The shoulder belt section (10) has a structure in which, upon inflation, the head-side portion (10S) becomes thicker than the front portion (10F), and the front portion (10F) becomes substantially even in thickness in the longitudinal direction.

Description

technical field [0001] The present invention relates to an inflatable occupant restraint belt capable of restraining an occupant seated on a vehicle seat and an occupant restraint device having the occupant restraint belt. Background technique [0002] As an occupant restraint device that restrains an occupant sitting on a vehicle seat with an inflatable belt, the following occupant restraint device is known: a shoulder anchor provided on the vehicle rear side of the seat and a The anchor is pulled around to the occupant restraint belt on the front side of the occupant, and in the occupant restraint belt, at least the part provided on the side of the occupant's head is an inflatable part (for example, JP-A-2003-312439). [0003] In the occupant restraint device (air belt device) of the above-mentioned Japanese Unexamined Patent Application Publication No. 2003-312439, the shoulder anchor is installed on the upper part of the pillar portion located obliquely behind the vehicl...
