Abstract
Abstract The device for vertical adjustment of a safety belt fitting consists of a load-receiving guide rail and an anchoring element which is vertically displaceable in said rail and to which the safety belt fitting is anchored. Said anchoring element carries a load-receiving stop portion which cooperates with spring-loaded pawls which project into the linear path of movement of said rigid stop portion unless they are pressed by a release element into their release position. Said release position comprises apart from an actuating extension a blocking extension which in the actuated state of the release element projects into the path of movement of the rigid stop portion and consequently also cooperates with the pawls. Unintentional skipping of the respective next lower detent position is made impossible by this construction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
189 words
A device for the height adjustment of a safety belt fitting in motor vehicles, comprising a load-receiving guide rail adapted to be mounted in a vehicle, an anchoring element which is displaceably accommodated in said guide rail and to which said safety belt fitting is secured, a detent means comprising a plurality of pawl members spaced apart in the longitudinal direction of said guide rail which pawl members are movable against spring force out of a normal locking position into a release position, a latch element on said anchoring element cooperating with said pawl members for locking engagement therewith, and a release element for releasing the locking between said latch element and said pawl members in an actuated state thereof, said release element being mounted on said anchoring element and having a blocking extension which in the actuated state of said release element and upon downward displacement of said anchoring element engages the first pawl member encountered on said downward movement to stop downward displacement of said anchoring element, said pawl members when in said release position being located out of the path of movement of said blocking extension.
Claim 2
Independent Claim
189 words
A device for the height adjustment of a safety belt fitting in motor vehicles, comprising a load-receiving guide rail adapted to be mounted in a vehicle, an anchoring element which is displaceably accommodated in said guide rail and to which said safety belt fitting is secured, a detent means comprising a plurality of pawl members spaced apart in the longitudinal direction of said guide rail which pawl members are movable against spring force out of a normal locking position into a release position, a latch element on said anchoring element cooperating with said pawl members for locking engagement therewith, and a release element for releasing the locking between said latch element and said pawl members in an actuated state thereof, said release element being mounted on said anchoring element and having a blocking extension which in the actuated state of said release element and upon downward displacement of said anchoring element engages the first pawl member encountered on said downward movement to stop downward displacement of said anchoring element, said pawl members when in said release position being located out of the path of movement of said blocking extension.
Claim 3
Independent Claim
202 words
A device for the height adjustment of a safety belt fitting in motor vehicles, comprising a load-receiving guide rail adapted to be mounted in a vehicle, an anchoring element which is displaceably accommodated in said guide rail and to which said safety belt fitting is secured, and a detent means comprising a plurality of detent element spaced apart in the longitudinal direction of said guide rail, a latch element on said anchoring element cooperating with said detent elements for locking engagement therewith, and a release element releasing the locking between said latch element and said detent elements in an actuated state thereof, said release element comprising a blocking extension which in the actuated state of said release element and upon a downward displacement of said anchoring element describes a path which meets any of said detent elements which is the first detent element encountered on said downward movement to be stopped at said first detent element, said detent elements with the exception of a lowermost one of said detent elements being each formed as a pawl member which is movable against spring force out of a normal locking position into a release position out of said path described by said blocking extension.
Claim 4
Independent Claim
202 words
A device for the height adjustment of a safety belt fitting in motor vehicles, comprising a load-receiving guide rail adapted to be mounted in a vehicle, an anchoring element which is displaceably accommodated in said guide rail and to which said safety belt fitting is secured, and a detent means comprising a plurality of detent element spaced apart in the longitudinal direction of said guide rail, a latch element on said anchoring element cooperating with said detent elements for locking engagement therewith, and a release element releasing the locking between said latch element and said detent elements in an actuated state thereof, said release element comprising a blocking extension which in the actuated state of said release element and upon a downward displacement of said anchoring element describes a path which meets any of said detent elements which is the first detent element encountered on said downward movement to be stopped at said first detent element, said detent elements with the exception of a lowermost one of said detent elements being each formed as a pawl member which is movable against spring force out of a normal locking position into a release position out of said path described by said blocking extension.
Claim 5
Dependent Claim
31 words
The device according to claim 2, wherein said latch element includes a rigid stop portion having a path of movement into which said detent elements project in their normal locking positions.
Claim 6
Dependent Claim
31 words
The device according to claim 2, wherein said release element comprises an actuating extension which in the actuated state of the release element presses the detent element into its release position.
Claim 7
Dependent Claim
24 words
The device according to claim 4, wherein said blocking extension and said actuating extension are disposed on a same arm of said release element.
Claim 8
Dependent Claim
23 words
The device according to claim 2, wherein said release element is formed as a lever which is pivotally mounted on said anchoring element.
Claim 9
Dependent Claim
25 words
The device according to claim 6, wherein said release element comprises an actuating arm and a second arm on which said blocking extension is formed.
Claim 10
Dependent Claim
18 words
The device according to claim 6, wherein said release element has a pivot range limited by stop members.
Claim 11
Dependent Claim
31 words
The device according to claim 2, wherein a lowermost of said detent elements is formed as a rigid stationary detent element projecting into an inner space defined by said guide rail.
