ABSTRACT:
A reclining device for a seat comprises a first plate fixed to a seat portion, a second plate fixed to a back rest and pivoted to the first plate to permit forward and rearward reclining movements of the back rest, a toothed member secured to the second plate, and a pawl member pivoted to the first plate and movable between a locked position in which the pawl member engages the toothed member and an unlocked position in which the pawl member disengages from the toothed member. The reclining device further includes a hand lever pivoted to the first plate and operatively connected with the pawl member to move the pawl member toward the unlocked position, a cam element integrally provided with the hand lever and engageable with the bottom face of the pawl member to hold the pawl member in the locked position, a foot lever pivoted to the first plate coaxially with the pawl member and interlocked with the hand lever, and a spring biasing the hand lever toward a released position to engage the cam element with the pawl member. In the assembly, the pawl member and the cam element are arranged in a common vertical plane with the toothed member and the hand and foot levers are arranged in a common vertical plane with the second plate, thereby to reduce the width of the reclining device.
