Abstract
Abstract An apparatus for setting a fitting element which is adjustable relative to a support element to various positions, particularly a fitting element for vehicle seats is disclosed. The apparatus includes a locking device which is self-arresting under a load from the return force and having at least two locking elements which engage each other by teeth means which prevent movement of the fitting element, one of said locking elements positioned on the fitting element and the other of said locking elements being movably guided on the support element and movable forcibly only into the locking position against a return force by means of said activating member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
An apparatus for setting a fitting element which is adjustable relative to a support element to various positions, particularly for vehicle seats comprising: a locking device which is self-arresting under a load from a return force which tends to move the fitting element into an end position of its range of adjustment and which has at least two locking elements that engage each other by teeth in order to prevent movement of the fitting element, one of the locking elements being a detent disc positioned on the fitting element, and said other of the locking elements being a detent member movably guided on the support element and also being movable forcibly only into a locking position against a reset force by an activating member.
Claim 2
Independent Claim
124 words
An apparatus for setting a fitting element which is adjustable relative to a support element to various positions, particularly for vehicle seats comprising: a locking device which is self-arresting under a load from a return force which tends to move the fitting element into an end position of its range of adjustment and which has at least two locking elements that engage each other by teeth in order to prevent movement of the fitting element, one of the locking elements being a detent disc positioned on the fitting element, and said other of the locking elements being a detent member movably guided on the support element and also being movable forcibly only into a locking position against a reset force by an activating member.
Claim 3
Dependent Claim
56 words
Apparatus according to claim 1, wherein at least tooth flanks of the teeth of the locking elements which abut each other under a load from the return force have an inclined angle relative to the direction of movement of the movably guided locking element dtent member which is at least equal to the resting frictional angle.
Claim 4
Dependent Claim
14 words
Apparatus according to claim 2, wherein the teeth are of a saw tooth shape.
Claim 5
Dependent Claim
12 words
Apparatus according to claim 1, wherein the detent member is a slide.
Claim 6
Dependent Claim
22 words
Apparatus according to claim 1, wherein the detent member which can be moved by the activating member is formed by a latch.
Claim 7
Dependent Claim
19 words
Apparatus according to claim 5, wherein only the latch has a tooth shape which fulfills the condition for self-arresting.
Claim 8
Dependent Claim
32 words
Apparatus according to claim 1, further comprising: at least one spring means, which acts on the locking device, for producing the return force and which can be moved by the activating member.
Claim 9
Dependent Claim
137 words
Apparatus according to claim 1, adapted for an articulated fitting of a motor vehicle in which the fitting element which is adjustable to change the angle of inclination of a backrest is rotatably mounted on the support element connected with a lower seat portion and in which the locking device is provided which in an unlocked position allows a movement of the backrest relative to the support element even when the detent member is in engagement with the teeth of the detent disc, further comprising a pre-biased return spring means for producing a return force, said spring means acting on the support element and on the fitting element, and which spring means exerts a force thereon in the sense of a return of the fitting element into the position corresponding to the steepest setting of the backrest.
Claim 10
Dependent Claim
75 words
Apparatus according to claim 1 for setting a fitting element for the height adjustment of a vehicle seat, wherein an adjustable fitting element is provided with teeth formed as a guide which is pivotably mounted on the support element associated with a lower seat portion and which is hingedly coupled with an upholstery support to transfer its rotational movement into an adjusting movement of the upholstery support of the vehicle seat having a vertical component.
