A vehicle seat includes a foam body having a first region, a second region, a top surface, and a bottom surface, and a trench defined by and between the first and second regions. The trench includes at least one section including a narrow portion having a first width and extending downwardly into the trench from the top surface, and a base portion below the narrow portion having a second width greater than the first width. The vehicle seat further includes a trim attachment fixture disposed in the foam body below the trench, wherein the trim attachment fixture is configured to be secured to a trim cover by an attachment member disposed in the base portion.

A vehicle seat comprises a seating portion and a back rest the angle of inclination is adjustable in relation to the seating portion, where at least the back rest is of modular design made of a plurality of upholstered elements, the upholstered elements each comprising a preformed foam part surrounded, at least in part, by a cushion cover, the upholstered elements made in this manner are put together via fasteners in modular fashion to form the back rest adjustable in inclination.

A vehicle seating assembly includes a cushion supported by a seat frame and a retention device disposed laterally through the cushion in front of a predetermined H-point so as to be able to restrain a seated occupant. The retention device is selectively deployable from a design position to a deployed position in response to a sudden deceleration of a vehicle.

The present invention provides a seat formed by bonding a trim cover to a foam pad, in which a sewing part of a trim cover can be bonded to a foam pad even when the trim cover is of leather. In a seat formed by bonding a trim cover to a foam pad, the trim cover includes a sewing part where plural trim covers are sewn up, raw material that is impregnated with an adhesive is sewn to the sewing part, and the foam pad and the raw material having been sewn are bonded to each other by the adhesive.

A method of making a trim article includes the steps of 1) obtaining specified criteria of a target component part comprised of a plurality of materials; 2) processing the specified criteria into a design envelope that includes parameters of the target component part within which the trim article to be created is to be confined, 3) inputting the design envelope into an additive manufacturing device supplied with a single forming material; and 4) forming the trim article using the additive manufacturing device from the single material. The formed trim article includes an outer casing with an interior portion having one or more lattice matrices disposed therein and having varying density profiles to simulate the specified criteria of the target component part. The formed trim article is created as a fully integrated monolithic whole via the additive manufacturing device.

A trim article includes an outer casing having an inner surface defining an interior portion of the outer casing. The outer casing includes a front surface having a plurality of through apertures disposed thereon. A core portion is disposed within the interior portion of the outer casing and includes first and second portions having variated densities relative to one another. The first and second portions include lattice matrices having variated patterns of interconnected links and associated cells that provide variated force deflection parameters between the first and second portions of the core portion. The outer casing and the core portion are integrated to define a monolithic structure comprised of a common material.

A seat assembly includes a seat portion and a seatback. A cushioned component is disposed in either the seat portion or the seatback. The cushioned component includes a porous lattice matrix and non-porous first and second walls that are disposed within and surrounded by the lattice matrix. The first and second walls are spaced-apart from one another and disposed at opposed angles to define a channel therebetween. The lattice matrix and the first and second walls are deformable structures for supporting a seat occupant while still being able to channel air through the cushioned component. The lattice matrix and the first and second walls are contemplated to be integrally formed components defining a monolithic structure. The lattice matrix may include multiple sets of spaced-apart walls for channeling air through different portions of the cushioned component.

A seat trim cover having a 3-dimensional shape for an automotive vehicle seat is formed by pre-cutting a laminate blank into a predefined shape having a predefined selvage extending around an outer periphery of the laminate blank, vacuum forming the laminate blank in a 3-dimensional mold to form a 3-dimensional laminate blank, and forming a molded foam backing on the 3-dimensional shaped laminate blank to form the seat trim cover. The molded foam backing has an outer perimeter that is spaced apart from the predefined selvage such that the predefined selvage is free of foam.

Disclosed is a vehicular seat element comprising a first major surface, a second major surface and a foam core element disposed therebetween. The first major surface is configured to be in contact with an occupant of the vehicle and the second major surface is configured to be in contact with a support surface of the vehicle. The first major surface comprises a rate sensitive foam element secured with respect to the foam core element. The foam core element and the rate sensitive foam element are different from one another.

A seat core material of the present invention is a seat core material for vehicle including a thermoplastic resin expanded bead article and a frame member embedded in a peripheral edge portion of the expanded bead article. The frame member includes a front frame part, a rear frame part, and two side frame parts interconnecting the front frame part and the rear frame part. Slits crossing the two side frame parts are formed along a longitudinal direction with continuous parts left intact outside the side frame parts on both ends of the expanded bead article. The slit penetrates or does not penetrate the expanded bead article in a thickness direction. The continuous parts are formed in a curved shape or a bent shape.
