Abstract: A woven fabric for a seat belt comprises warp and weft yarns which are combined to constitute a woven base which extends in a given way, and extra yarns which are held in the woven base and extend substantially straightly along the given way. The extra yarns are constructed of a material whose extensibility is lower than that of materials of the warp and weft yarns and whose tensile strength is higher than that of the materials of the warp and weft yarns.

Abstract: A seat slide device including a lower light-alloy guide rail rigidly mounted on a floor panel through a leg member attached to the lower rail, an upper light-alloy guide rail which is slidably fitted to the lower rail and firmly secured to the bottom of a seat, and bearings rotatably disposed between the upper and lower rails, comprises a reinforcement arranged along the inner wall of the rear end of the lower rail for enhancing a rigidity of the rear end. The leg member is arranged along the outer wall of the rear end of the lower rail in a position where the reinforcement and the lower rail are overlapped with each other so that the three members are stratified to each other. The three-stratified members are integrally coupled to each other by fastening rivets. The reinforcement is integrally formed with a bearing stopper restricting a maximum rearward displacement of the bearings.

Abstract: An airbag of an airbag restraint system mounted on an automotive vehicle and adapted to protect a vehicle passenger in a serious vehicle collision. The airbag is formed of a cloth which is basically constituted of warp and weft yarns made of a high melting point polymer material. Low melting point polymer yarns are woven in the cloth in a manner to extend along the warp and weft yarns. The low melting point polymer yarns are located at predetermined intervals, and have a melting point lower than that of the high melting point polymer material. The low melting point polymer yarns melt upon heating in a heat treatment so as to be welded to the high warp and weft yarns thereby securely binding the warp yarns together and the weft yarns together.

The stationary rail has a first bottom wall portion, first inside wall portions vertically upwardly extending from side ends of the first bottom wall portion, upper wall portions outwardly extending from upper ends of the first inside wall portions, and first outside wall portions vertically downwardly extending from outer ends of the upper wall portions. Each of the upper wall portions is grooved at a major portion thereof for receiving ball bearings thereon and convexly curved at a rear end portion thereof. The major portion and the rear end portion are united.

Abstract: A seat reclining mechanism for adjusting the angular position of a seatback relative to a seat cushion by a planetary gear arrangement includes a rotatable shaft, a base plate, a pivotable arm, a control gear, a plurality of planetary gears, and a supporting member. The pivotable arm is rotatably connected to the base plate through the rotatable shaft. Each planetary gear has two opposed cylindrical projections which are outwardly biased by the supporting member against cylindrical smooth surfaces of cylindrical recesses formed on the base plate and the pivotable arm. Therefore, the planetary gears are held in a predetermined revolution orbit around the control gear.

Abstract: A suspension seat for an automotive vehicle includes a seat frame which is vertically movably supported on a parallel link mechanism having front and rear links. A compression spring and a shock absorber are coaxially combined and installed between an upper and back side portion of the seat frame and an arm portion connected to the rear link. Therefore, the suspension seat sufficiently absorbs an impact force while keeping small a space between the seat and the floor.

Abstract: As a cutter having first and second cutter blades is driven toward a molded ceiling consisting of a base material and a surface material which is attached to the base material in a stretched state, the surface material is first cut by the first cutter blade which is adapted to cut the molded ceiling at a position outside of a predetermined trimming or cutting position such that the trimmed or cut end of the surface material is inclined to have a flat triangular sectional shape. Then, the inclined end of the surface material is cut off together with an excess portion of the base material by means of the second cutter blade which is adapted to cut the molded ceiling at the predetermined trimming or cutting position.

Abstract: An airbag restraint system for protecting a vehicle passenger in the event of a vehicle serious collision. An airbag of this system is usually folded compactly and is covered with a generally box-shaped cover member. The cover member has openings at the central portion and the side center portion of a rectangular top surface of the cover member. A plurality of thin portions, which are thinner in thickness than that of the main portion, are formed along the center line parallel to the long side of the top surface and along every sides of the top surface. In the event of the vehicle serious collision, the cover member is easily broken from the end of the thin portion defining the opening.
