A vehicle seat having a seat cover including an outer cover, a padding layer, and a backing element that are joined together with stitches or a lamination joint. A seat cover retention apparatus is operatively connected to the backing element wherein a plurality of straps secure the backing element to the vehicle seat structure. Lateral side straps are secured to the backing element and extend through openings defined by the foam bun and are secured to the frame and/or the foam bun. A center strap is secured to the backing element and extends through a center opening to be secured to a back side of the foam bun and/or frame. The backing element may be an elastic strap or a layer of non-woven fleece material with slits for the straps. The straps may be elastic material or non-woven material.

A vehicle seat comprising a foam padding having a through-bore, a surface cover element covering a surface of the foam padding, and a functional element formed from a soft material. The functional element has a tubular body fitted in the through-bore of the foam padding and a flange integral with the tubular body. An area of the flange of the functional element, adjacent to a peripheral end of the flange, is sewn with a reverse side of an edge portion of an opening defined in the surface cover element, such reverse side facing to the foam padding. The surface cover element with the flange thus sewn therewith covers the foam padding, with the tubular body being fitted in the through-bore of the foam padding, so that a surface of the flange and an opening of the tubular body are exposed in an outer surface of the vehicle seat.

A method of applying stitching to an outer skin layer of an interior component is provided herein, the outer skin layer having a contoured surface. The method including the steps of: a) penetrating the contoured surface of the outer skin layer at an entry point on a first surface of the contoured surface of the outer skin layer with a curved needle; b) exiting the contoured surface of the outer skin layer at an exit point on the first surface with the curved needle, wherein the steps of penetrating and exiting cause a first thread to pass through the entry point and the exit point on the contoured surface of the outer skin layer; c) grabbing the first thread with a hook located proximate to the exit point; d) retracting the needle through the exit point and the entry point while pulling a second thread through the exit point via the first thread to form a stitch; e) advancing the contoured surface of the outer skin layer to a new location with respect to the needle and hook; and f) repeating steps a-e until a predetermined amount of stitches are applied to the contoured surface of the outer skin layer.

A structure of wadded-up seat trim cover, having a plurality of trim cover pieces sewn together at one end, each composed of a wadding member and a skin member, includes a bonded portion formed by bonding the skin member to the wadding member made shorter than the skin member, at a position remote, by a prescribed distance, from the end of the wadding member overlapping the skin member; a first sewn portion formed by bending that portion of the skin member, not overlapping the wadding member, along the end of the wadding member and then by sewing the portions of the adjacent skin members together; and second sewn portions formed by bending each end of the adjacent skin member to the back of the trim cover piece at the first sewn portion and then by sewing the adjacent skin members together at overlapping portions.

A vehicle seat incorporating a side airbag includes a seat cushion and a seat back, if an impact is detected at that side of the seat back, the inflator is activated, generating high-pressure gas, the gas gushes in the airbag, inflating the airbag, and the airbag so inflated tears up the sewn part of the seat back, which are positioned at the front part of the vehicle wall side of the seat back, and develops to the side and front of the occupant, isolating the occupant from the vehicle wall and protecting the occupant; and the airbag is secured to the inner side of the side frame on the vehicle wall side, an expansion restriction plate is provided on the inner side of the airbag, and the airbag is sandwiched between the side frame on the vehicle wall side and the expansion restriction plate.

A vehicle seat includes a pair of anchors able to engage with engagement members provided on a child seat; a pad having a pair of pad recesses for storing anchors, a trim cover having openings above the pad recesses; and a pair of bezels being hollow cylinder shaped, each having an upper edge flange sewn at the outer edge to the terminal of the trim cover, and covering and hiding the associated pad recess, and each bezel is made of flexible material and has a lower edge flange formed integral with a lower end thereof capable of inserting into the pad recess, the pad has an engaging section capable of engaging with the lower edge flange, the lower edge flange may be deformed and inserted into the pad recess in order to make the bezel cover the pad recess, and the lower edge flange may restore its original shape.
