Abstract

An adjustably lockable hinge for motor-vehicle seats comprises first and second hinge elements and a pintle between these elements defining a pivot axis therefor. A first arcuate row of equispaced first abutments is carried on the first element spaced from the main axis and facing axially in one direction. A body carrying a second arcuate row of equispaced second abutments facing axially from the body opposite to the one direction and axially aligned with the first row is rotationally linked to the second element. The abutments of the second row are spaced apart by a predetermined distance different from the spacing between the first elements, so that only a limited number of the second abutments can mesh at one time with the first abutments. An adjustment device rotatable about the axis relative to the elements is engageable with the body for precession of the second row on the first row. These rows may be annular arrays of gear-type teeth and the body may be a ring around the hinge pintle.

Dependent claims

An adjustably lockable hinge comprising:

first and second adjacent hinge elements;
a pintle between said elements defining a pivot axis therefor;
a first arcuate row of equispaced first abutments fixed on said first element spaced from and centered on said axis and facing axially in one direction;
a body having a second arcuate row of equispaced second abutments facing axially from said body opposite to said one direction and axially aligned with said first row, said abutments of said second row being centered on a precession axis intersecting said pivot axis and being spaced apart by a distance different from the spacing between said first abutments, whereby said rows can precess and only a limited number of said second abutments can mesh at one time with said first abutments;
means rotationally linking said body with said second element to permit for joint angular movement about said pivot axis;
and
means rotatable about said pivot axis relative to said elements and engageable with said body to cause said second abutments to roll on said first abutments to produce precession of said second row on said first row.
