Benefits of technology

[0010] By means of these provisions, occupant safety is improved relative to the safety procured with known padding, without the improvement being achieved to the detriment of comfort.

Problems solved by technology

The presence of visco-elastic foam degrades the degree of comfort offered by the seat.
However, the padding described in that document similarly does not make it possible to optimize the comfort and the anti-submarining effect, e.g. in a manner adapted to the geometrical shape of the seat proper.

Embodiment Construction

[0027] In the various figures, like references designate elements that are identical or similar.

[0028]FIG. 1 shows a motor vehicle seat 1 that, in a manner known per se, is made up of a seat proper 2 supporting a seat back 3 that itself supports a headrest 4.

[0029] The seat back 3 is, for example, mounted to pivot about the pivot axis A (FIG. 2) on the seat proper 2.

[0030] The seat proper 2 is itself constituted by a framework (not shown) over which elastic suspension webbing 5 is tensioned. The webbing supports padding 6 which is itself covered with a trim cover 7 suitable for being sat upon by a passenger of the motor vehicle on board which the seat 1 is installed.

[0031] The padding 6 extends longitudinally along the axis (x) relative to the direction in which the seat extends between a front end 8 remote from the seat back 3 and a rear end 9 close to said seat back. The seat proper can thus be subdivided into three portions, namely a rear portion 6a, an intermediate portion 6...

Abstract

Padding for the seat proper of a seat, the padding comprising a visco-elastic foam and a comfort foam. The visco-elastic foam extends between a bottom face of the seat proper and an intermediate level of the padding. The comfort foam extends between the intermediate level and the top face of the seat proper. The comfort foam and the visco-elastic foam extend both over the rear and over the front of the seat proper.

Description

FIELD OF THE INVENTION [0001] The present invention relates to padding for the seat proper of a vehicle seat. [0002] More particularly, the invention relates to padding for the seat proper of a vehicle seat, the padding extending in a longitudinal direction between a front portion and a rear portion serving to receive the pelvis of an occupant sitting on the seat, and in a vertical direction, between a bottom surface designed to face towards a vehicle floor, and a top surface designed to face towards the body of the occupant, said padding comprising at least: [0003] a comfort foam that is soft both when the seat is in normal use, and when the vehicle decelerates suddenly; and [0004] a visco-elastic foam that is stiffer when the vehicle decelerates suddenly than when the vehicle is in normal use; [0005] said visco-elastic foam extending from the bottom surface, and said comfort foam, secured to said visco-elastic foam, extending to the top surface of the padding.
