Abstract
An inclinable headrest includes a base bracket including first and second side walls, a ratchet gear, and a lock gear movable for engagement with the ratchet gear. Both ratchet and lock gears are disposed inwardly of the first and second side walls. The lock gear has a connecting hole. The first side wall of the base bracket has an opening defined at a location where the connecting hole of the lock gear exists, and a connecting region defined near to that opening. Provision of those opening and connecting regions allows direct and quick connection by a worker's hand of a tension spring between the lock gear and base bracket from the outside, such that the worker can directly engage one end of the tension spring with the lock gear's connecting hole through the opening, while directly engaging the other end thereof with the base bracket's connecting region.
