Disclosed is a fastening structure for a seating foam, comprising a foam and a reinforcement fabric, and characterized in that the fastening structure is directly provided at a reinforcement fabric at a location corresponding to a fastening position, and is connected to the reinforcement fabric. The fastening structure of the present invention simultaneously meets two functional requirements of a foam, namely reinforcement of a side B of the foam and fastening of an exterior side A of the foam. The novel fastening structure of the present invention saves space, is thin and light, enhances the strength of the foam against a pull-out force, and optimizes a foam production process.

The present invention provides a vehicle seat with little fine creases on a concave portion of a seat surface even the use of natural leather such as a cowhide as a skin material for the vehicle seat. A vehicle seat includes a seat cushion making a seated portion of the seat; a seat back disposed at a back side of the seat cushion and making a backrest portion of the seat; and a cover formed of a cloth including a skin material, an adhesive material, and a cushion material at a concave portion on at least one surface among the seat cushion and the seat back. The cover is formed into a concave shape by heat presswork with a mold having a curved surface.

A recessed seam structure for a cover (3) that improves workability when forming a recessed seam (A) and allows frequent attachment and detachment at the recessed seam (A) is provided. In a seat (1) having the recessed seam (A) formed by pulling part of the cover (3) toward a side of a cushion material (2), the recessed seam (A) is provided with an opening and closing fastener (30) configured to couple the cover (3) and the cushion material (2), and the opening and closing fastener (30) includes a first fastener half (31) fixed to a back face of the cover (3) and a second fastener half (32) fixed to the cushion material (2). In such a seat (1), the recessed seam (A) can be formed easily and reliably on the seat (1) by aligning an end of the first fastener half (31) in a longitudinal direction and an end of the second fastener half (32) in the longitudinal direction of the opening and closing fastener (30) and simply sliding a slider (33).

To improve comfort, a motor vehicle seat has at least one cushion body, at least one cover concealing the cushion body at least in part, and at least one tensioner, which is operatively connected to the cover by a first end and is designed to adjust the cover tension. The tensioner is fixed by a second end to a clamping device. The clamping device is designed to modify and fix the distance of the tensioner from the first end thereof to the second end thereof and the clamping device is designed to be operated after completion of the motor vehicle seat.

A support element for a vehicle seat, the support element including: a shell, a cover mounted on the shell, the cover defining a front surface for receiving a passenger, and a rear surface opposite the front surface, and a padding arranged between the shell and the cover. The cover has a plurality of fastening loops fastened on the rear surface of the cover. The shell has a plurality of through-openings arranged substantially facing the fastening loops, the fastening loops passing through the through-openings and mechanically cooperating with the shell so as to keep the cover rigidly connected to the shell.

A ISOFIX guide element, having a base section, a rear side section, and two side sections connected to the base, an insertion opening, which is delimited by respective inner sides of the base section and the two side sections, a bracket opening formed between the base section and the rear side section which has notches formed in the side sections in such a way that a bracket-like fixing element can be accommodated in the notches, and that the fixing element is accessible through the insertion opening. It is provided here that at least one fastening element protruding from the base section is arranged on an outer side of the base section, wherein the fastening element has at least one oblong-hole-type fastening opening, which is connectable to a tab of a seat cushion or a seat cover of a vehicle seat.

A vehicle seat cushion carrier assembly (bottom and back) via which a cushion carrier structure, cushion foam, and upholstery are more easily assembled and installed in a vehicle, optionally as a modular unit. The cushion carrier structure can be multi-piece and incorporate any desired trim units. Strap fasteners are used to secure the upholstery to the cushion carrier structure and cushion foam, creating the desired creating seams, creases, and indentations. Clip fasteners are used to secure the upholstery to the cushion carrier structure around the cushion foam, especially with respect to the seat back. This allows much of the upholstering to be done outside the vehicle, optionally in a modular manner. Finally, these modular features and functionalities allow the cushion carrier assemblies (bottom and back) to be quickly and easily secured to the underlying seat pan and/or seat frame using simple screws, hooks, and clip fasteners.

A seat back configured to support a back of a seated person includes a back frame constituting an internal framework; and an elastic mat fitted to the back frame so as to cover the back frame from a front side, the elastic mat having a planar shape and being configured to elastically support the back of the seated person. The back frame includes a frame body and a support wire that protrudes forward from the frame body. The elastic mat includes a main support portion configured to support the back of the seated person, and a band portion that extends from a back surface of the main support portion, the band portion being wound around the support wire. The elastic mat has a through-hole through which a head at a distal end of the wound band portion is inserted such that the head is snap-fitted in the through-hole.

To improve comfort, a motor vehicle seat has at least one cushion body, at least one cover concealing the cushion body at least in part, and at least one tensioner, which is operatively connected to the cover by a first end and is designed to adjust the cover tension. The tensioner is fixed by a second end to a clamping device. The clamping device is designed to modify and fix the distance of the tensioner from the first end thereof to the second end thereof and the clamping device is designed to be operated after completion of the motor vehicle seat.
