Problems solved by technology

[0014] In the airbag device described in the above-mentioned Patent Document 1, there is a problem that base fabrics with different stretching degrees need to be arranged and connected in parallel, the structure becomes complicated, and the tethers must be separately produced according to the stretching characteristics of the airbag, resulting in cost. The main reason for the rise

Abstract

Provided are a tension member for an airbag, and an airbag device which are configured so that a tensile force can be continuously controlled using a simple configuration. An airbag device is provided with an airbag (2) which is usually folded and which is inflated and expanded in an emergency, an inflator (3) which supplies gas to the airbag (2), a retainer (4) which affixes the airbag (2) and the inflator (3), and a tension member (5) for an airbag, the tension member controlling the shape or the function of the airbag (2) by a tensile force. The tension member (5) for an airbag has: both end sections (51) which are connected to portions capable of moving relative to each other when the airbag (2) is inflated and expanded; an expanded-width section (52) which is formed at an intermediate section between both end sections (51); and a breaking section (53) which is formed along the direction of extension of the expanded-width section (52) and which breaks depending on the magnitude of a tensile force occurring between both end sections (51).

Description

technical field [0001] The present invention relates to an airbag stretching member and an airbag device, and more particularly to an airbag stretching member and an airbag device suitable for controlling the inflated and expanded shape of the airbag, the opening and closing of a vent hole, and the like. Background technique [0002] Vehicles such as automobiles are generally equipped with an airbag device for inflating and deploying an airbag inside the vehicle to absorb the impact on the occupant in an emergency such as a collision or sudden deceleration. The above-mentioned airbag device has been developed and adopted, including a driver's airbag device built in the steering device, a passenger airbag device built in the instrument panel, a side airbag device built in the side of the vehicle or a seat, and a curtain type airbag device built in the upper part of the door. There are various types of airbag devices, knee airbag devices corresponding to the occupant's knees, ...
