Abstract
Abstract The invention relates to a device for setting elements which are pivotable relative to each other, especially for setting the pivotable upholstery support of a headrest for vehicle seats, having at least two elements which are not movable in the direction of the axis of rotation which are movable relative to each other about the axis of rotation and at least one setting member which form-fittingly locks these elements in the desired rotational position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
132 words
Device for setting elements which are pivotable relative to each other, especially for setting the pivotable upholstery support of a headrest for vehicle seats, comprising: a first element formed as a pipe-like hollow tube; a second element engaged with said first element and formed as at least one rod-like support bar; a setting member arranged in said first element so as to be longitudinally movable therein; an activator device associated with said setting member to form an adjusting device; and guide means for engaging said second element with said first element; whereby a forced pivotal motion of at least one of the first and second elements relative to the other is produced when the setting member is moved by the activator device in the longitudinal direction of the first element relative thereto.
Claim 2
Dependent Claim
132 words
Device for setting elements which are pivotable relative to each other, especially for setting the pivotable upholstery support of a headrest for vehicle seats, comprising: a first element formed as a pipe-like hollow tube; a second element engaged with said first element and formed as at least one rod-like support bar; a setting member arranged in said first element so as to be longitudinally movable therein; an activator device associated with said setting member to form an adjusting device; and guide means for engaging said second element with said first element; whereby a forced pivotal motion of at least one of the first and second elements relative to the other is produced when the setting member is moved by the activator device in the longitudinal direction of the first element relative thereto.
Claim 3
Dependent Claim
46 words
Device according to claim 1, wherein said guide means comprise at least two guides and characterized in that at least one of the two guides, which are form-fitted in the direction of rotation, extends in a spiral, in whose longitudinal axis lies the axis of rotation.
Claim 4
Dependent Claim
20 words
Device according to claim 2, characterized in that one of the two guides runs parallel to the axis of rotation.
Claim 5
Dependent Claim
38 words
Device according to claim 3, characterized in that at least one of the two guides is formed by at least one groove and by at least a number of projections, which number corresponds to the number of grooves.
Claim 6
Dependent Claim
19 words
Device according to claim 4, characterized in that the at least one groove is provided in the setting member.
Claim 7
Dependent Claim
27 words
Device according to claim 4, characterized in that at least some of the number of projections are formed on the first element and are formed as ribs.
Claim 8
Dependent Claim
26 words
Device according to claim 6, characterized in that an end portion of the second element engaged in the first element lies wholly within said first element.
Claim 9
Dependent Claim
42 words
Device according to claim 3, characterized in that the guide running parallel to the axis of rotation is formed by an inner cover surface of the first element and by at least part of an outer cover surface of the setting member.
Claim 10
Dependent Claim
29 words
Device according to claim 1, characterized in that an end portion of the second element engaged in the first element lies in a longitudinal channel of the setting member.
Claim 11
Dependent Claim
72 words
Device according to claim 9, characterized in that the setting member has an opening for the second element engaged in the first element, said opening located in a wall between an outer cover surface and the longitudinal channel of said setting member towards which the guide means for the second element is open, and said opening also being directed toward an opening in a side of a cover of the first element.
Claim 12
Dependent Claim
40 words
Device according to claim 1, characterized in that the second element engages with the first element through an opening in a side of a cover of said first element and is pivotably mounted in a wall area of said opening.
Claim 13
Dependent Claim
78 words
Device according to claim 11, characterized in that the setting member lies at a distance from the wall area containing the opening in the side of the cover of the first element and further characterized in that the guide means receives an end portion of the second element introduced through the opening and is opened toward an outer cover surface of the setting member lying opposite the opening in the side of the cover of the first element.
