Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A device for actuating door safety lock latches of automotive vehicles, for central locking systems, comprising a door latch actuating rod projecting from a box-like body and movable between a raised position and a lowered position, an electric motor controlling the movement of said rod by means of a kinematic chain comprising an elastic connecting pawl disengageable from said rod, characterized in that said pawl is pivoted on a slide solid with said rod and cooperates with a cursor through two operating surfaces co-acting with a respective pair of surfaces of said cursor and a third surface co-acting with two surfaces of said slide so that, when the rod is in the raised position, cursor and pawl are in engagement with a first pair of surfaces so as to permit movement of the rod - either manually or by the motor - to the lowered position, in which cursor and pawl are in engagement with a second pair of surfaces so as to permit either manual or motor-operated raising of said rod, terminal arrest means cooperating with said cursor and said slide.
Claim 2
Independent Claim
182 words
A device for actuating door safety lock latches of automotive vehicles, for central locking systems, comprising a door latch actuating rod projecting from a box-like body and movable between a raised position and a lowered position, an electric motor controlling the movement of said rod by means of a kinematic chain comprising an elastic connecting pawl disengageable from said rod, characterized in that said pawl is pivoted on a slide solid with said rod and cooperates with a cursor through two operating surfaces co-acting with a respective pair of surfaces of said cursor and a third surface co-acting with two surfaces of said slide so that, when the rod is in the raised position, cursor and pawl are in engagement with a first pair of surfaces so as to permit movement of the rod - either manually or by the motor - to the lowered position, in which cursor and pawl are in engagement with a second pair of surfaces so as to permit either manual or motor-operated raising of said rod, terminal arrest means cooperating with said cursor and said slide.
Claim 3
Dependent Claim
32 words
A device according to claim 1, characterized in that said kinematic chain consistes of at least one pair of gears and screw-nut screw in which said nut-screw is formed in said cursor.
Claim 4
Independent Claim
29 words
A device according to claims 1 and 2, characterized in that said electric motor and said screw have parallel axes and are operationally linked through a pair of gears.
Claim 5
Independent Claim
33 words
A device according to claims 1 and 2, characterized in that said terminal arrest means consist of walls of said box-like body and are either centred or adjacent with respect to said screw.
Claim 6
Dependent Claim
20 words
A device according to claim 1, characterized in that said box-like body is closed at its base by a stopper.
Claim 7
Dependent Claim
28 words
A device according to claim 1, characterized in that said pawl is made elastic through the agency of a needle spring acting between said slide and said pawl.
