Abstract
A high-rigidity recliner according to the present invention comprises an upper actuating member attached to a seat base, and a lower actuating member attached to a seat back and is characterized by the upper actuating member supporting a pair of symmetrical lock gears fixedly interposed between a cam and a lower actuating member. Outer gear parts of the lock gears engage inner gear parts of the lower actuating member, whereby any clearances between the outer gear parts and inner gear parts are eliminated and any irreular engagement of the outer and inner gear parts is prevented. The lock gears lock or release the lower actuating member by rotation of the actuating cam. The simple structure of the present invention reduces the number of parts, the time for assembly, and the cost of manufacturing. Additionally, forming the outer and inner gears by blanking improves strength and durability of the recliner.
