US 7,243,992 B2 · Vehicle seat structure, and a vehicle provided with a seat having such a structure

Abstract

The structure of the seat proper of a vehicle seat comprises: a frame for a seat proper, the frame including a side cheek plate; and a coupling system comprising a link mounted to pivot on a base to enable the seat proper to move at least vertically relative to said base. The coupling system has a first latch surface. The seat structure further comprises an anchoring element provided with a second latch surface. The anchoring element is mounted to move on the cheek plate between a locked position and an unlocked position.

A system comprising a seat belt and a structure for a motor vehicle seat proper, the structure comprising:

a rigid frame for said seat proper, the frame extending between a front portion and a rear portion, the frame including a side cheek plate extending from said rear portion of the rigid frame to said front portion of the rigid frame;
and
a coupling system comprising a link having a bottom portion mounted to pivot on a base and a top portion mounted to pivot relative to the rear portion of said rigid frame about a first pivot axis so that said bottom portion of the link pivoting relative to said base in a third direction causes said rear portion of the rigid frame to move at least vertically upward relative to said base;
said coupling system having an axial connection member secured to said top portion of the link, and mounted to pivot relative to said cheek plate;
and a ring constrained to rotate with the axial connection member and having a first latch surface, so that said first latch surface is constrained to rotate with the link;
said seat structure further comprising an anchoring element provided with a second latch surface and to which said seatbelt is directly secured;
and wherein the anchoring element is mounted to pivot on said rigid frame about a second pivot axis distinct from the first axis, said anchoring element being adapted so that traction exerted by said seatbelt on the anchoring element along a seatbelt traction axis causes the anchoring element to pivot about the second axis in a second direction, from an unlocked position in which the second latch surface of said anchoring element is held at some distance away from the first latch surface of the coupling system by return means exerting forces in a first direction of rotation opposite to the second direction of rotation, and secondly to a locked position in which the second latch surface co-operates with the first latch surface to prevent the bottom portion of the link from pivoting in said third direction relative to said base.

#The present invention relates to vehicle seat structures.

#More particularly, the invention relates to a structure for a vehicle seat proper, the structure comprising: a rigid frame for a seat proper, the frame including at least one side cheek plate extending between a front portion and a rear portion; and a coupling system comprising a link having a bottom portion mounted to pivot on a base and a top portion mounted to pivot relative to the rear portion of said cheek plate about a first pivot axis so that said bottom portion of the link pivoting relative to said base causes said rear portion of the seat proper to move at least vertically relative to said base; said coupling system having a first latch surface.

#On a vehicle seat including a seat proper provided with such a structure, a user can adjust the vertical position (the height) of the seat proper relative to the floor, thereby enabling users of different sizes to occupy the seat under conditions that are good for each of them. A seat with a seat proper whose height is adjustable is described, for example, in French Patent Application FR 2 737 868. That seat is provided with four such links coupled together in pairs between two side cheek plates of the seat frame.

#In the various figures, like references designate elements that are identical or similar.

#As shown diagrammatically in FIG. 1, the invention relates to a vehicle seat 1, in particular a motor vehicle front seat.

#The seat comprises firstly a seat proper 2 which extends in a “longitudinal” direction between a rear end and a front end, and secondly a seat back 3 which is generally mounted to pivot relative to the seat proper.
