Embodiment Construction

[0089] Embodiments of the present invention will be described below with reference to the drawings.

[0090] First, a side airbag system according to a first embodiment of the present invention will be explained. Such as figure 1 As shown, a side airbag system 10 according to a first embodiment of the present invention includes a side airbag 12 and an inflator 14 .

[0091] Such as figure 2 As shown, the side airbag 12 has an upper bladder portion 16 , a lower bladder portion 18 , a belt portion 22 and a tube 24 . Such as figure 1 As shown, the side airbag 12 is folded and accommodated in a side portion of a seat back 28 in a vehicle seat 26 , for example normally. In the event of a side collision, the side airbag 12 is supplied with gas from the inflator 14 to inflate and deploy to the lateral sides of the occupant 30 seated on the vehicle seat 26 . Please be aware of, figure 1 A dummy is shown as the occupant 30 .

[0092] The upper bladder portion 16 is formed of a ...

Abstract

In a side airbag system (10), a tether portion (22), which serves as a partition between an upper bag portion (16) and a lower bag portion (18), is formed of upper regions (34U) of a piece of lower base fabric (34), and is formed by sewing the upper regions (34U) of the lower base fabric (34), folded toward a vehicle front side along a fold axis, together. In addition, a tube (24) that distributes inflation gas between the upper bag portion (16) and the lower bag portion (18) extends through the tether portion (22) to the lower bag portion (18) and to the upper bag portion (16). The tube (24)is formed into a cylindrical shape in such a manner that a piece of tube base fabric (36) is sewed to the upper regions (34U) of the lower base fabric (34) and folded toward a vehicle front side along the fold axis and then front ends (36F) of the folded tube base fabric are sewed together in a tube longitudinal direction.

Description

technical field [0001] The invention relates to a side airbag system and a method for producing a side airbag. Background technique [0002] For example, a Japanese translation of the publication of PCT Application No. 2003-501303 (JP-A-2003-501303) describes a side airbag. The side airbag includes a cushion and an inflatable tube. The cushion has an inflatable upper chamber and an inflatable lower chamber separated by a separator plate. The expandable tube is positioned adjacent to the cushion and is positioned adjacent to one of the bottom side and the rear side of the cushion to extend at least a partial extent of the cushion before the inflation gas safely inflates the cushion . [0003] However, the separation panel described in JP-A-2003-501303 is formed separately from a plurality of base fabrics of the airbag, and the peripheral edges of the separation panel are sewn to two pieces of the airbag base fabric. This work of sewing the separating panels is complicated...
