Device for adjusting inclined position of seats, particularly motor vehicle seats

A seat position adjuster for seats, particularly for motor vehicle seats having a guiding track assembly mounted on the floor of the vehicle and a seat carrier pivotably connected at one end thereof to said guiding track assembly, comprising:

• guiding slots formed opposite each other in the lateral sides at the other end of said seat carrier;
• a transverse shaft supported for movement in said slots;
• holding brackets secured to said guiding track assembly opposite to said slots and each defining a vertical cutout having at one side thereof a plurality of superposed recesses adapted for receiving said shaft and at the other side thereof a passage permitting free movement of said shaft;
• gear segments connected to said brackets along said passage in said cutout;
• pinions supported for rotation on respective ends of said transverse shaft opposite said gear segments;
• and hand-operated and spring-biased linkage coupled to said shaft for normally urging the latter into a selected one of said superposed recesses and for displacing said shaft in said guiding slot for permitting free movement of said shaft in said vertical cutout when actuated, said linkage including a pivot axle supported for rotation on said seat carrier, an elbow lever having its apex connected for joint rotation with said transverse pivot axle, a link coupled between one arm of said elbow lever and said shaft, and a tension spring arranged between the other arm of said elbow lever and said seat carrier to urge said linkage and said shaft in the arresting direction.

A seat position adjuster for seats, particularly for motor vehicle seats having a guiding track assembly mounted on the floor of the vehicles and a seat carrier pivotably connected at one end thereof to said guiding track assembly, comprising:

• juxtaposed bearing brackets connected to said guiding track assembly opposite said one end of said seat carrier and each including a collar bushing pivotably supporting said one end of said seat carrier;
• guiding slots formed opposite each other in the lateral sides at the other end of said seat carrier;
• a transverse shaft supported for movement in said slots;
• holding brackets secured to said guiding track assembly opposite to said slots and each defining a vertical cutout having at one side thereof a plurality of superposed recesses adapted for receiving said shaft and at the other side thereof a passage permitting free movement of said shaft;
• gear segments connected to said brackets along said passage in said cutout;
• pinions supported for rotation on respective ends of said transverse shaft opposite said gear segments;
• and hand-operated and spring-biased linkage coupled to said shaft for normally urging the latter into a selected one of said superposed recesses and for displacing said shaft in said guiding slot for permitting free movement of said shaft in said vertical cutout when actuated.

• a rocking arm supported by each of said holding brackets and hinged below said cutout, said rocking arm defining a vertical slot extending in the range of said cutout;
• gear segments connected to said brackets along said passage in said cutout secured to said rocking arms along one side of said vertical slot;
• pinions supported for rotation on respective ends of said transverse shaft opposite said gear segments and being in permanent engagement with said gear segments;
• and hand-operated and spring-biased linkage coupled to said shaft for normally urging the latter into a selected one of said superposed recesses and for displacing said shaft in said guiding slot for permitting free movement of said shaft in said vertical cutout when actuated.

• gear segments connected to said brackets along said passage in said cutout, said cutout and respectively said gear segments being curved about a pivot axle at said one end of said seat carrier, said gear segments and said other side of said cutout being located closer to said pivot axle than said holding recesses;
• pinions supported for rotation on respective ends of said transverse shaft opposite said gear segments;
• and hand-operated and spring-biased linkage coupled to said shaft for normally urging the latter into a selected one of said superposed recesses and for displacing said shaft in said guiding slot for permitting free movement of said shaft in said vertical cutout when actuated.
