Abstract
Abstract The device serves to fasten the edge (7) of the cover (6) of the cushion constituting a seat back (5) to the outer flange of a channel (4) that is open towards the rear and that is provided at the edge of a plate (3) constituting framework for said cushion, the fastening device comprising a J-section member (9) attached to the edge of said cover. Said flange is firstly extended outwardly by a lateral gutter (10, 11) that is open in the opposite direction to the channel, and secondly it has a series of holes (12) punched out therein so as to form a corresponding number of tabs (13) extending parallel to the general plane of the plate, and towards the inside of the channel. The J-section member has a J-shaped head and a hook portion (14) that extends the large flap of the J-shape at right angles and that has a bead (16) formed on one side thereof such that when fastened, the hook is located astride the series of punched-out tabs while the extension and its bead are placed in contact with the outer flange (11) of the gutter.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
202 words
A device for fastening an edge of a cover covering a cushion of a seat to a series of planar tabs, each tab being punched out from a channel which faces away from the seat cushion and is located on an outside edge of a plate forming a part of a frame of said seat and extending parallel to the plate towards the inside of the channel, each tab including a base which is extended outwardly from the channel by a continuous rim that is coplanar with each tab, and wherein the continuous rim is extended by a lip folded at a right angle thereto and cooperating with the rim to form a lateral gutter that is open towards the cushion, the device comprising a J-section member having a hook-shaped curved portion which includes a large, flat portion; and an extension that extends the large, flat portion at a right angle to the hook-shaped curved portion, the extension being attached along the edge of the cover and including a bead extending parallel to the hook-shaped curved portion such that, when fastened, the hook-shaped curved portion is disposed astride the tab and the extension and its bead fits over and abuts the lip.
Claim 2
Independent Claim
202 words
A device for fastening an edge of a cover covering a cushion of a seat to a series of planar tabs, each tab being punched out from a channel which faces away from the seat cushion and is located on an outside edge of a plate forming a part of a frame of said seat and extending parallel to the plate towards the inside of the channel, each tab including a base which is extended outwardly from the channel by a continuous rim that is coplanar with each tab, and wherein the continuous rim is extended by a lip folded at a right angle thereto and cooperating with the rim to form a lateral gutter that is open towards the cushion, the device comprising a J-section member having a hook-shaped curved portion which includes a large, flat portion; and an extension that extends the large, flat portion at a right angle to the hook-shaped curved portion, the extension being attached along the edge of the cover and including a bead extending parallel to the hook-shaped curved portion such that, when fastened, the hook-shaped curved portion is disposed astride the tab and the extension and its bead fits over and abuts the lip.
Claim 3
Dependent Claim
60 words
A fastening device according to claim 1, characterized in that the channel includes an inside flange connected to a lateral strip of the plate, the plate having an outside face of which the furthest-projecting portion lies in the same plane as an outside face of a head portion of the attached-together cover edge and J-section member placed astride the tabs.
Claim 4
Dependent Claim
40 words
A fastening device according to claim 1, characterized in that spikes are punched out from the channel to co-operate for locking purposes with an outside catch provided at a free end of the hook-shaped curved portion of the J-section member.
Claim 5
Dependent Claim
29 words
A fastening device according to claim 1, characterized in that the J-section member includes a narrowed zone between its hook-shaped curved portion and its extension, thereby forming a hinge.
Claim 6
Dependent Claim
127 words
A fastening device according to claim 1, applied to covers for seat backs having independently foldable portions and suitable for constituting a vehicle backseat, characterized in that a channel-and-gutter side assembly of a given back portion having a baseplate and being disposed adjacent to another back portion including a frame, is formed in the baseplate of said given back portion simultaneously with an adjacent, symmetrical channel-and-gutter lateral assembly being formed in an adjacent plate for constituting a base of the frame of said other back portion of the backseat, said two assemblies being formed by stamping and cutting out a single common main plate suitable for use as the frame base for the back of a vehicle backseat that is not subdivisible into independently foldable back portions.
Claim 7
Dependent Claim
30 words
A main plate according to claim 5, characterized in that it includes two parallel channels stamped side by side in an intermediate zone and united by means of a bridge.
