Abstract
The round hinged-part comprises a fixed flange having a central opening receiving a main piece supporting a cam on which is mounted a double satellite with inner and outer tooth sets cooperating respectively with tooth sets of the fixed and movable flanges, a circular cut-off part of the fixed flange is used as a common centering path for the double satellite and for a central ovoid ring, and a ball-bearing is interposed between the movable flange and a ring mounted between the movable flange and the fixed flange.
Claims16
Hinge apparatus for seats used in land, sea and air-vehicles, comprising:
- a housing constituting first and second circular flanges, and means for coupling said first and second flanges together for relative rotation,
- said first flange (1) adapted to be fixed to a first portion of a seat and having in its center an opening receiving a main piece (2) supporting a cam on which a double satellite gear is mounted,
- said second flange being adapted to be secured to a second portion of the seat,
- the double satellite gear including an inner tooth set (5a) and an outer tooth set (5b), one of said two tooth sets cooperating with an outer tooth set (8a) of the first flange (1) and the other of said two tooth sets cooperating with an inner tooth set (9a) of the second flange (9),
- said first flange further having annular means facing said second flange for centering said double satellite gear (5) and a central ovoid ring (13) between said first and second flanges,
- first bearing means (12) interposed between the second flange (9) and a rim for securing the second flange (9) to the first flange (1),
- second bearing means (15,16) interposed between the annular centering means (1b), the central ovoid ring (13) and a needle ball race (14) serving as a resting piece for the double satellite gear (5) relative to the cam (4),
- opposing faces of the first flange (1) and the second flange (9) including means, communicating with the interior of said housing, for securing said hinge apparatus to the first and second portions of the seat,
- the central main piece (2) having a central portion with a circular recess and a plain bearing for receiving means for driving the mechanism of the hinge apparatus.
A hinge assembly for pivotably connecting a seat back of a vehicle seat with the frame of the vehicle seat, comprising:
- two circular hinge parts rotatable relative to one another about a pivot axis between a plurality of relative positions;
- means for coupling the peripheries of said hinge parts to form a housing;
- and
- means for selectively adjusting the relative position between said hinge parts, said adjusting means including
- first eccentric means having an aperture centered on said pivot axis, said eccentric means being carried by one of said two hinge parts for rotation therewith,
- first gear means carried by one of said hinge parts,
- second gear means carried by the other of said hinge parts,
- third gear means, supported between said hinge parts, having gearing means for interengaging said one hinge part with said other hinge part
- locking means carried within said housing and engagable with one of said hinge parts for preventing movement of said one hinge part, and
- operator means supported by, and including a portion disposed within, said housing, said operator means comprising means for selectively moving said locking means into and out of engagement with said one hinge part,
- whereby said locking means may be selectively moved into engagement with said one hinge part to lock said hinge parts in one of said plurality of relative positions.
