Claim 8

In an adjustment system for automobile vehicle seats and including two parallel slides, each slide having a U-shaped male section having at least one outwardly extending flange at an upper edge, a U-shaped female section slidingly receiving said male section, and each slide having a locking mechanism, said locking mechanism comprising: a one piece unitary member lock lock for securing the male and female sections together, the lock having a fixed first end fastened to the female section, an intermediate flexible, portion extending from the fixed end, and a vertically moveable second end portion extending from the flexible portion; the moveable portion having a locking flange extending through a window formed in an upper surface of the female section; a set of locking teeth formed in the locking flange that removably mate with a plurality of notches formed in an upper edge of the at least one outwardly extending flange of the male section when the male and female sections are secured together; moveable unlocking device means mounted to the locks of each slide for freeing engagement of the locking teeth with the notches when the intermediate flexible portion is elastically deflected upwards at each slide, the unlocking device means having a U-shaped bar with two arms rotatably mounted at their ends on pivots extending laterally from the female sections; the moveable portion further having a generally U-shaped cross section including two arms, the first of which is the locking flange oriented to face downward, the second arm juxtaposed against an outward surface of the female section and includes a connector for receiving the unlocking device means.

Claim 9

The adjustment system set forth in claim 6 wherein each pivot is integrally formed with a folded portion extending from a respective fixed end of a corresponding lock, the folded portion resting against a correspondingly positioned female section flange.

Claim 10

The system set forth in claim 7 wherein the connector is a clip integrally formed from the second arm of the U-shaped moveable portion and extending transversely therefrom.

Claim 11

The system set forth in claim 7 wherein the unlocking device bar is normally biased in a locked position by the intermediate flexible portion that is elastically deformed.

Claim 12

A vehicle seat adjustment system having at least two tracks, each track comprising: a stationary female member; a male member slidably mounted in the female member; a one piece unitary member lock locking device for removably securing the male member in the female member, the device having a first end secured to the female member, an intermediate flexible section, and a vertically displaceable second end section; the second end section having an L-shaped flange received within a slot formed in an upper surface of the female member, a set of teeth longitudinally extending along a bend in the flange and normally engaging a) a row of longitudinally extending notches formed in an upper surface portion of the male member; and b) a row of longitudinally extending notches formed in a flange return of the female member, the return underlying an outwardly extending flange of the male member; whereby vertical displacement of the locking device removes the teeth from the engaged notches thereby allowing sliding movement of the male member within the female member.

Claim 13

A vehicle seat adjustment system having at least two tracks, each track comprising: a stationary female member; a male member slidably mounted in the female member; a one piece unitary member lock locking device for removably securing the male member in the female member, the device having a first end secured to the female member, an intermediate flexible section, and a vertically displaceable second end section; the second end section having an L-shaped flange received within a slot formed in an upper surface of the female member, a set of teeth longitudinally extending along a bend in the flange and normally engaging a) a row of longitudinally extending notches formed in an upper surface portion of the male member; and b) a row of longitudinally extending notches formed in a flange return of the female member, the return underlying an outwardly extending flange of the male member; whereby vertical displacement of the locking device removes the teeth from the engaged notches thereby allowing sliding movement of the male member within the female member.

Claim 14

A vehicle seat adjustment system having at least two tracks, each track comprising: a stationary female member; a male member slidably mounted in the female member; a unitary locking device for removably securing the male member in the female member, the device having a first end secured to the female member, an intermediate flexible section, and a vertically displaceable second end section; the second end section having an L-shaped flange received within a slot formed in an upper surface of the female member, a first set of teeth longitudinally extending along a bend in the flange and a second set of teeth longitudinally extending along an outer edge of the flange, the two sets of teeth normally respectively engaging a) two parallel rows of longitudinally formed notches in an upper surface portion of the male member; and b) two rows of longitudinally formed notches in flange returns of the female member, the returns underlying outwardly extending flanges of the male member; whereby vertical displacement of the locking device removes the teeth from the engaged notches thereby allowing sliding movement of the male member within the female member.

Claim 15

A vehicle seat adjustment system having at least two tracks, each track comprising: a stationary female member; a male member slidably mounted in the female member; a unitary locking device for removably securing the male member in the female member, the device having a first end secured to the female member, an intermediate flexible section, and a vertically displaceable second end section; the second end section having an L-shaped flange received within a slot formed in an upper surface of the female member, a first set of teeth longitudinally extending along a bend in the flange and a second set of teeth longitudinally extending along an outer edge of the flange, the two sets of teeth normally respectively engaging a) two parallel rows of longitudinally formed notches in an upper surface portion of the male member; and b) two rows of longitudinally formed notches in flange returns of the female member, the returns underlying outwardly extending flanges of the male member; whereby vertical displacement of the locking device removes the teeth from the engaged notches thereby allowing sliding movement of the male member within the female member.
