摘要:
An airbag (10) has a first tier of material (11) and a second tier of material (12). The second tier (12) at least partially overlaps the first tier (11). The first and second tiers (11, 12) are joined together by one or more rows of a sealed stitch seam (20). The sealed stitch seam (20) has a plurality of thread stitches (30) extending from one exterior side (14) through to the opposite exterior side (16) of the at least partially overlapped first and second tiers (11, 12). The thread stitches (30) are coated in each exterior side (14, 16) with a seam coating material (40). The seam coating material (40) is either applied over the stitches (30) on one exterior side (14 or 16) and flows through to the opposite side (14 or 16) through thread holes (52) formed upon the creation of the seam (20) or is applied to both exterior sides (14, 16) and flows into the thread holes (52) to encapsulate and seal the seam (20).
摘要:
A protection device with an inflatable element apt to assume an active inflated condition and a rest deflated condition. The inflatable element includes a knitted body having a closed structure on at least four sides or walls and having a partially tubular shape to define an inner area or inner chamber. The knitted body includes a plurality of union threads occupying at least partially the inner area and apt to connect two faces or walls of the knitted body.

An object of the present invention is to provide an airbag device configured such that, when an inflator is operated, gas is less likely to leak outside from an insertion hole which is formed on a cushion and into which the inflator is inserted. An airbag device 100 is installed in a vehicle and includes: a bag-shaped cushion 108 which inflates and deploys using gas supplied from a cylinder-type inflator 110; an insertion hole 112 which is formed on the cushion and through which the inflator is inserted into the cushion; and a covering part 120 which is provided on an inner side of the cushion and which covers the insertion hole. The covering part includes: a first cloth 122 which is provided at a position overlapping the insertion hole and on which a slit 126 that is elongated in one direction is formed; and a second cloth 124 which is provided so as to overlap with the first cloth and on which a slot 128 is formed so as to have a longitudinal direction in a direction intersecting a longitudinal direction of the slit at a position overlapping the insertion hole.
摘要:
Airbags including tethered inflatable chambers are disclosed. The tethered inflatable chambers can include internal tethers that are configured to break when an internal pressure of a tethered inflatable chamber reaches a predetermined value. Methods of forming an airbag fabric including internal tethers are also disclosed.
摘要:
A fabric for an air-bag comprising interwoven sets of warp and weft yarns, wherein the yarns of one of the sets of yarns are tape-like, having a width/depth ratio of at least 1.5, and the yarns of the other set of yarns are not tape-like and have a width-depth ratio less than 1.5.
摘要:
The aim of the invention is to provide a seam for an airbag and an airbag comprising such a seam which keeps stresses produced in the airbag material approximately at the seam end to a minimum when the airbag is inflated while simultaneously allowing the targeted reduction of the size of the chamber formed by the loop. For this purpose, a seam is provided comprising a neck section which is made of a forward seam and a rearward seam. The forward seam and the rearward seam run next to each other substantially in a straight line in the neck section. The seam also comprises a head section in which the forward seam and the rearward seam are connected together. The forward seam and the rearward seam each has a curvature between the neck section and the head section, and the curvature of the forward seam and the curvature of the rearward seam have substantially the same orientation such that a transition section with a curved progression is formed between the neck section and the head section.
摘要:
An air-bag (1) for use in a vehicle, the air-bag (1) comprising a fabric layer (10) comprising a plurality of interwoven warp and weft yarns; an additional layer (15a) which is at least partly superimposed on a part of the fabric layer (10); and an intermediate layer (16) which is at least partly positioned between the fabric layer (10) and the additional layer (15a), the intermediate layer (16) comprising a mesh structure which is provided with a plurality of cells (17), wherein the cells (17) contain a matter having a lower thermal conductivity than the warp and weft yarns of the fabric layer (10).
摘要:
A process for modifying a silicone elastomeric-based surface of an article where the coefficient of friction (COF) of the silicone elastomeric-based surface is generally reduced by at least 5% is disclosed. The process comprises subjecting the silicone elastomeric-based surface of the article to vacuum ultraviolet (UV) radiation.
摘要:
An article is described that includes at least one fibrous support surface coated by at least two successive layers including: an inner layer, in contact with the fibrous support, which is a coating including a silicone elastomer, polyurethane or silicone-polyurethane; and a topcoat outer layer, in contact with the inner layer, which is a coating obtained by crosslinking a composition described herein. The first layer, that is in contact with the fibrous support, is a layer based on a silicone elastomer, polyurethane or silicone-polyurethane composition that was crosslinked. The second layer, that is in contact with the first layer, is a layer obtained by crosslinking as described herein.
