ABSTRACT:
An adjustment device for incrementally adjusting the inclination of a backrest member of a vehicle seat assembly, which backrest member is pivotably mounted with respect to a seat member.
The adjustment device comprises a first hinge bracket rigidly secured to one of the members and a second hinge bracket rigidly secured to the other of the members, wherein the one of said first and second hinge brackets which is connected to the backrest member is pivotally moveable with respect to the other of said first and second hinge brackets. A first gear means is mounted on the first hinge bracket and is operationally connected to the second hinge bracket so as to effect the pivotal movement of the backrest member. A drive means is operationally connected to the first gear means and a control means is operationally connected to the drive means for activation thereof. A locking means is operationally connected to the drive means to resist movement of the drive means, the locking means comprising a first abutment face adapted for co-operation with an opposed second abutment face, the abutment faces providing respective mutually engageable abutment means which, in response to activation of the drive means by the control means, are brought into and out of engagement, thereby defining a series of inclination adjustment positions of the backrest member.
