Abstract
Abstract A seat padding, in particular for a motor vehicle seat backrest, includes a foam block whose support face has a recess closed by a base towards the opposite face, and filled with an insert of material permeable to air and/or moisture. The recess is arranged between two lining return grooves defining two re-entrant lines in the cover surrounding the padding and symmetrical with respect to the vertical mid-plane of the padding. The recess is separated from the grooves by two respective shoulders made of a hard foam.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
A seat padding comprising: a foam block having a support face, an opposite face, and a recess provided in said support face; a base adjacent said opposite face which closes said recess; at least two lining return grooves in said support face with said recess therebetween, said return grooves being substantially symmetrical to each other with respect to a longitudinal vertical mid-plane of the seat padding such that said two lining grooves define two re-entrant lines for a cover used to surround the seat padding; two respective partitions which transversely separate respective said grooves from said recess and which are made of a hard foam material, each said partition including a free end distal from said base which is adapted to be engaged by the cover emerging from an associated said lining groove and stretched over said recess; and an insert which fills said recess, said insert being made from a material which is more permeable to one of air or moisture than a material of said foam block.
Claim 2
Dependent Claim
169 words
A seat padding comprising: a foam block having a support face, an opposite face, and a recess provided in said support face; a base adjacent said opposite face which closes said recess; at least two lining return grooves in said support face with said recess therebetween, said return grooves being substantially symmetrical to each other with respect to a longitudinal vertical mid-plane of the seat padding such that said two lining grooves define two re-entrant lines for a cover used to surround the seat padding; two respective partitions which transversely separate respective said grooves from said recess and which are made of a hard foam material, each said partition including a free end distal from said base which is adapted to be engaged by the cover emerging from an associated said lining groove and stretched over said recess; and an insert which fills said recess, said insert being made from a material which is more permeable to one of air or moisture than a material of said foam block.

Dependent Claim
58 words
A seat padding as claimed in claim 1 and further including: a third partition which transversely joins said two partitions so as to form an open U-shaped frame; and a third return groove which is adjacent to and outside of said frame and running along said third partition which transversely separates said third return groove from said recess.
Claim 4
Dependent Claim

Claim 9
Dependent Claim
50 words
A seat padding as claimed in claim 1 wherein said foam block includes side parts which are separated from said two partitions by said two return grooves; and wherein said side parts and said base are made of a foam at least substantially as hard as that of said partitions.
