AI Technical Summary

Technical Problem

In existing vehicle seats, the timing for the airbag bulge to tear and deploy is delayed due to the delay in transmitting tension to the reinforcing fabric, which is partially extended before the bulging portion, leading to a slight delay in the tearing of the bulge portion.

Method used

A vehicle seat design where the reinforcing fabric is fixed to a latch member on the seat cushion side, with its other end attached to a hanging member positioned more inward than a folding portion, allowing quick transmission of tension to the bulging portion during airbag inflation.

Benefits of technology

The bulging portion tears more quickly, enabling the airbag to deploy smoothly and protect the occupant earlier by ensuring rapid transmission of the reinforcing fabric's pulling force.

Abstract

A vehicle seat comprising a seat cushion (6P) forming an outline of the seat and elastically supporting an occupant, a seat cover (6S) covering the seat cushion (6P), and an airbag (10) inflatable by the inflow of air, wherein: a plurality of cover pieces (SP1, SP2, SP3, SP4) are sewn together to form the seat cover (6S); the airbag (10) is adapted to bulge out of the seat from a bulging portion (30) formed by sewing together adjacent cover pieces (SP3, SP4); a strip-shaped reinforcing fabric (36) which is harder to stretch than the seat cover (6S) is arranged around the airbag (10) on a back side of the seat cover (6S); the bulging portion (30) is caused to expand by stretching the reinforcing fabric (36) which accompanies the inflation of the airbag (10) accompanied by tearing, a suspension element (32) which is harder to stretch than the seat cover (6S) is attached to a part of the seat cover (6S);a folding section (38), which is a part of the seat cover (6S) and to which the hanging element (32) is attached, is pulled into the seat; and one end of the reinforcing fabric (36) is attached to the bulge section side; characterized in that: the hanging element (32) is locked to a locking element (34) on the seat cushion side; at a position further inside the seat than the folding section (38), the further end of the reinforcing fabric (36) is attached to either only the locking element (34) or only the hanging element (32) and the locking element (34);
