A device for ventilating the occupant of a vehicle seat, comprising an air inlet receiving air from a ventilation member, and comprising a first duct integrated at least in part into the backrest of the seat, a second duct integrated into a headrest mounted on the seat and supplying at least one air outlet integrated into the headrest and expelling air coming from the ventilation member, the second duct and first duct being connected by a leaktight sliding connection.

A vehicle seat back may include an integrated suspension structure including a suspension wire and suspension mounting guides coupled to both sides of the suspension wire; and a seat back pad foamed for integrating with the integrated suspension structure in a state in which the integrated suspension structure is inserted into a mold for seat back pad formation.

A vehicle seat has a lower seat part and a seat backrest. The seat backrest has a backrest structure, a central backrest section which has at least one backrest cushion and a backrest cover, and a left and a right backrest side wall. The seat backrest is provided with at least one expansion element which has at least one cavity that is enclosed by a membrane and can be filled with an expansion fluid from a fluid source. At least one respective fillable cavity of the at least one expansion element is integrated into the backrest cushion of the central backrest section or is provided between the backrest structure and the backrest cushion of the central backrest section to the left and the right of the backrest longitudinal central plane at a lateral distance thereto.

The present invention relates to support apparatus for supporting at least a portion of a gluteal region of a user while the user is seated in a seating apparatus comprising a seating surface, a back support surface and a transition region at the intersection of the seating surface and the back support surface. The support apparatus a support member structured to support at least a portion of the gluteal region of the user. The support apparatus further comprises a support element structured to position the support member at the transition region of seating apparatus such that the support member extends between the seating surface and the back support surface of the seating apparatus.

Compound padding having comfort layer and providing good support is revealed. The compound padding includes a support layer and at least one comfort layer. The support layer is a foam layer made of low-density melamine resin foam with certain support while the comfort layer is a foam layer made of hydrophilic polyurethane foam and attached to at least one surface of the support layer by an adhesive layer. Thereby the compound padding can provide effective support to user's body by the support layer and gives a good feeling and a sense of comfort to users by the comfort layer when users' skin is in contact with the compound padding. The compound padding has the advantages of low density, light weight and reduced cost.

The invention relates to an upholstered part of a vehicle seat (100), at least including a foam part (12-2) which, in a foaming process, forms a permanent connection to a prefabricated shaped nonwoven (12-1), wherein the prefabricated shaped nonwoven (12-1) forms a supporting structure for the foam part (12-2). It is provided that the prefabricated shaped nonwoven (12-1′) has at least one locally situated open cavity (12-11′) which at least in sections is filled with foam, so that the foam part (12-2′) has a foam-embedded supporting and reinforcing structure at least in one section (11B′) of the cavity (12-11′).

A seat belt device for a vehicle seat, having a seat belt, the belt tongue of which in an engaged state is releasably connected to a seat-side belt buckle. The belt buckle is guided via at least one wire rope through a sleeve-like deflection element, which defines the course of the wire rope between its connection point on the seat side and its connection point on the belt buckle side. The sleeve-like deflection element has a predetermined deformation point, at which the deflection element is deformed in the event of a head-on collision, more specifically with the belt buckle being displaced from its use position into a crash position in which the tilt or twist moments acting on the belt buckle are reduced.

Provided is a cushion pad, in which a seating body portion of a seating portion has a bottomless or bottomed first hole arranged at a position at which the first hole overlaps a pair of ischial bones of a seated person in a horizontal projection plane and three or more bottomless or bottomed second holes with areas that are smaller than an area of the first hole in a horizontal projection plane, a center point O51 of the first hole is on or inside a triangle TR obtained by connecting center points of any three second holes from among the three or more second holes in the horizontal projection plane and in the seating portion, the inside of the first hole is a void space, or a soft material portion is arranged inside the first hole.
