## Abstract

A mounting system for a headrest comprising at least one shaft, the system comprising a housing adapted to enclose the shaft with a radial clearance, a moving carriage capable of being moved between a blocking position and an unblocking position, and a jaw movable between an immobilization position and a release position. The jaw is adapted to apply, when it is in the immobilization position, a clamping force to the shaft in a clamping direction perpendicular to the vertical direction, so that the shaft is supported on the housing. The moving carriage comprises at least one drive slot in which a slug from the jaw is able to move.

## Claims

### Claim 1

A mounting system for at least one shaft, the shaft extending in a vertical direction, the mounting system comprising:
a housing adapted to enclose the shaft with a radial clearance and
a moving carriage capable of being moved between a blocking position and an unblocking position,
at least a jaw movable between an immobilization position and a release position,
the jaw being driven by the moving carriage to be in the immobilization position when the moving carriage is in the blocking position and in the release position when the moving carriage is in the unblocking position,
the jaw being adapted to apply, when it is in the immobilization position, a clamping force to the shaft in a clamping direction perpendicular to the vertical direction, so that the shaft is supported on the housing,
wherein the moving carriage comprises at least one drive slot in which a slug from the jaw is able to move.

### Claim 2 (depends on 1)

The mounting system according to claim 1, wherein the moving carriage moves in the vertical direction between the blocking position and the unblocking position,
and wherein one portion at least from the drive slot is substantially inclined with respect to the vertical direction.

### Claim 3 (depends on 1)

The mounting system according to claim 1, wherein the jaw includes a flexible clamping member adapted to be in contact with the shaft and to apply the clamping force on said shaft, when the jaw is in the immobilization position.

### Claim 4 (depends on 3)

The mounting system according to claim 3, wherein the jaw includes at least one opening behind the flexible clamping member in order to allow the clamping member to flex by a predetermined value when it applies the clamping force.

### Claim 5 (depends on 1)

The mounting system according to claim 1, further comprising a return spring adapted to apply a force on the moving carriage in order to bring the carriage back into the blocking position.

### Claim 6 (depends on 1)

The mounting system according to claim 1, wherein the jaw and the housing form a single part, the jaw moving between the immobilization position and the release position by rotation using a flexible hinge.

### Claim 7 (depends on 1)

The mounting system according to claim 1, further comprising a lock that can be controlled by the moving carriage between a locking position and an unlocking position, said lock immobilizing the shaft in the vertical direction when it is in the locking position.

### Claim 8 (depends on 1)

An assembly including a headrest comprising at least one shaft extending in a vertical direction, as well as a mounting system of said shaft according to claim 1.

### Claim 9 (depends on 6)

An assembly including a headrest comprising at least one shaft extending in a vertical direction, as well as a mounting system of said shaft according to claim 6, wherein the shaft has at least one notch adapted to engage with the lock when it is in the locking position.

### Claim 10 (depends on 8)

A vehicle seat including a base, a backrest mounted on the base and an assembly according to claim 8 mounted on the backrest.
