Abstract: A reclining apparatus for adjusting a tilt angle between a first member and a second member includes: a base plate mounted to the first member; a gear plate mounted to the second member and assembled with the base plate rotatably relative to each other; a gear mechanism for controlling engagement of the gear plate with the base plate; and a cover having a first tubular portion fixed to an outer periphery of the base plate and a second tubular portion in slide contact with an outer periphery of the gear plate, the cover being configured to allow the base plate and the gear plate to rotate relative to each other and to suppress a relative movement therebetween in an axial direction. The first tubular portion is coupled by welding to the outer periphery of the base plate.

Abstract: In a case where a manipulation switch is manipulated when a limit switch detects the fact that the seat back is in an upright position, an ECU controls driving of a motor until a sector gear turned in a second turning direction moves a lock lever in a lock release direction at a second abutting portion thereby to cause a lock member to be in a lock release state. Also, in a case where the manipulation switch is manipulated when the limit switch detects the fact that the seat back is not in the upright position, the ECU controls driving of the motor until the limit switch detects the fact that the seat back is in the upright position.

Abstract: An internally-toothed plate 105 and an externally-toothed plate 106 are fitted together so that a portion of an externally-toothed gear 161 of the externally-toothed plate 106 is located in a recess 151 such that the externally-toothed gear 161 a meshes with an internally-toothed gear 151a, and so that a bearing portion 151b of the internally-toothed plate 105 is located in a recess 161. In other words, the externally-toothed plate 106 is fitted into the internally-toothed plate 105. At this time, a seat cushion bracket 121 to which the internally-toothed plate 105 is fixed by laser welding is in contact with an outer peripheral edge 163 at the back side of the recess 161 of the externally-toothed plate 106. As a result, a reclining device with a reduced number of components and size can be obtained.

Abstract: A reclining apparatus includes: a base plate on the first member; a gear plate on the second member and pivotably combined to the base plate; first and second guide portions on the base plate; first and second guide surfaces on the first guide portion; first and second guide surface on the second guide portion; first and second locking gear that are engageable with the gear plate; and a movable guide interposed between the first guide portion or the second guide portion and the first locking gear or the second locking gear. The first guide surface of the second guide portion faces the first locking gear. A recess is provided in the second guide surface of the first guide portion that orients the same pivotal direction as the first guide surface of the second guide portion to reduce a contact area with the second locking gear.

Abstract: An object of an aspect according to the present invention is to provide a reclining apparatus capable of reducing the cost. A center shaft of the reclining apparatus is inserted through through-holes respectively bored at the center portions of a base plate and a gear plate. The center shaft coaxially and pivotally supports the base plate and the gear plate. An annular protrusion provided at the center shaft is sandwiched between the base plate of the reclining apparatus and a bracket on a seat side. This prevents the center shaft from coming off.

Abstract: A seat slide device includes: a lower rail fixed to a vehicle body; an upper rail fixed to a seat and slidably fit into the lower rail; a lock member including an engaging portion that is engageable with an engaged portion of the lower rail for allowing the upper rail to be fixed to the lower rail; a biasing member for displacing the lock member such that the engaging portion is engaged with the engaged portion; a tilting member tiltably supported by the upper rail in contact with the lock member and tiltable in a predetermined direction for displacing the lock member so as to disengage the engaging portion from the engaged portion against a biasing force of the biasing member; and a contact portion being in frictional contact with the upper rail to allow a frictional force to act on the lock member.

Abstract: An object of the present invention is to provide a seat apparatus enabling noise reduction and size reduction of a rotation transmitting mechanism. This seat apparatus is provided with a rotation transmitting mechanism capable of transmitting rotation to each of adjusting mechanisms. This rotation transmitting mechanism includes a motor, a worm, and two worm wheels each meshed with the worm and arranged in proximity to each other. This rotation transmitting mechanism also includes four clutch members. Each clutch member is interposed between corresponding one of the adjusting mechanisms and corresponding one of the worm wheels. Each clutch member is configured such that it can be switched between a transmission state and an interruption state. In the transmission state, rotation via the worm wheel can be transmitted to the corresponding adjusting mechanism. In the interruption state, on the other hand, transmission of the rotation is interrupted.

Abstract: An object of an aspect according to the present invention is to provide a seat apparatus capable of automating inclination of a seat back by a simple configuration. In a case where a manipulation switch is manipulated when a limit switch detects the fact that the seat back is in an upright position, an ECU controls driving of a motor until a sector gear turned in a second turning direction moves a lock lever in a lock release direction at a second abutting portion thereby to cause a lock member to be in a lock release state. Also, in a case where the manipulation switch is manipulated when the limit switch detects the fact that the seat back is not in the upright position, the ECU controls driving of the motor until the limit switch detects the fact that the seat back is in the upright position.

Abstract: An impact absorbing plate 31 is disposed between a front part 31z of the impact absorbing plate 31 and a vehicle body 11 so that a rupture generating part 44 ruptured by impact is extended in the front and rear direction of the vehicle, and the impact absorbing plate 31 is fixed to a front part 13a and a rear part 13b of the front seat bracket 13 provided in the vehicle body by rivets 33 and 33. A portion of front part 31z of the impact absorbing plate 31 is cut to form a cutoff part 45, and a front end 17a of a rail 17 provided in a seat section is attached to a convex part 35, which is molded so as to expand upward an inner side of the cutoff part 45, by a rivet 34.
