Abstract

The invention relates to a vehicle seat with a seat padding (4), in particular for an aircraft seat, of the type comprising a supporting body (6) of foamed plastic, which consists of a supporting part (7) of a resilient plastic foam (42) having a first specific gravity and a sitting part (8) of a resilient plastic foam with a second specific gravity which is less than the specific gravity of the supporting part (7) and an upholstery material (62), which are connected, in particular are glued in places together. Between the supporting body (6) and the upholstery material (62), if required, a flame-resistant intermediate layer (51) formed from a lattice or from high temperature-resistant fibers or threads (52), is arranged in a lattice form. At least over a portion of the thickness (12) of the supporting part (7) and/or of the sitting part (8) between a front and/or back leading edge (11, 25) of the supporting part and/or sitting part (7, 8) and approximately in a central region thereof, an insert piece (9,84) is arranged. The latter has a greater hardness than the supporting and/or sitting part (7,8). The specific gravity of the insert piece (9,84) is less than the first specific gravity of the supporting part (7).

Dependent claims

A seat padding for a vehicle seat comprising a supporting body and an outer covering material, the supporting body extending from a front edge through a center region to a rear edge and having lateral edges defining the width of the supporting body, the front and rear edges defining the depth of the supporting body, and the supporting body comprising

(a) a supporting part of a resilient plastic foam having a first specific gravity, the supporting part having
(1) an upper side and
(2) an underside opposite the upper side,
(b) a sitting part of a resilient plastic foam having a second specific gravity which is less than the first specific gravity, the sitting part having
(1) an upper side and
(2) a bearing face opposite the upper side,
(3) the bearing face of the sitting part facing the upper side of the supporting part and
(4) the sitting part being superposed on the supporting part and being connected thereto, and
(c) an insert piece of resilient plastic foam forming a portion of the supporting part and being arranged between the front edge of the supporting body and about the center region thereof, the insert piece
(1) having a third specific gravity which is less than at least one of the specific gravities of the parts and a hardness greater than that of at least one of the parts,
(2) extending over at least a portion of the thickness of the supporting part, and
(3) having a connecting face facing a front end face of the supporting part, the connecting and front end faces being connected to each other.
