20090085390 | POSITIONING APPARATUS OF SEAT FOR VEHICLE - A positioning apparatus of a seat for a vehicle includes a first frame adapted to be supported by a member provided on a vehicle floor and adapted to support a seat cushion, a second frame rotatably supported by the first frame and vertically rotatably supporting the seat cushion, a link member rotatably supported by the first frame and linked to the second frame for rotatably moving the second frame relative to the first frame, and a rotational member rotatably supported by the first frame and including an eccentric shaft portion, wherein the eccentric shaft portion has a first rotational portion including a first rotational center about which the second frame rotates relative to the first frame and a second rotational portion including a second rotational center about which the rotational member rotates relative to the first frame and which is eccentrically provided relative to the first rotational center. | 04-02-2009 |
20090243327 | FEEDING APPARATUS - A feeding apparatus includes a screw shaft, a feeding nut, a supporting member, a driving unit, an intermediate member supported by the screw shaft and arranged to be rotatable relative to the supporting member, and an elastic biasing mechanism. The intermediate member includes a radial sliding contact surface slidably contacting a radial bearing surface of the supporting member, first and second thrust sliding contact surfaces contacting first and second thrust bearing surfaces formed at the supporting member, respectively. The elastic biasing mechanism elastically biases the first and second thrust sliding contact surfaces of the intermediate member to contact the first and second thrust bearing surfaces, respectively, and further elastically biases the intermediate member to a thrust receiving member provided at the screw shaft for assembling the intermediate member and the thrust receiving member onto the screw shaft without a clearance between the intermediate member and the thrust receiving member. | 10-01-2009 |
20100060061 | POWER SEAT DRIVING APPARATUS FOR VEHICLE - A power seat driving apparatus for a vehicle includes a moving unit and a decelerating mechanism. The deceleration mechanism includes a driving gear, a driven gear engaging with the driving gear and driven to rotate while decelerating a rotational speed of the driving gear, a supplemental gear coaxially connected to the driven gear in an interlocking manner, made of a resin material having elasticity and lower rigidity than the driven gear, having a larger tooth thickness than a tooth thickness of the driven gear by an amount corresponding to a backlash, and engaging the driving gear together with the driven gear, and a housing accommodating and rotatably supporting the driving gear, the driven gear and the supplemental gear. | 03-11-2010 |
20100060062 | POWER SEAT DRIVING APPARATUS FOR VEHICLE - A power seat driving apparatus for a vehicle includes a moving unit and a decelerating mechanism, wherein the decelerating mechanism includes a driving gear to which a driving force is inputted, a driven gear engaged with the driving gear so as to be rotatably driven by the driving gear while decelerating a rotational speed of the driving force transmitted thereto, and a housing, at least one of the driving gear and the driven gear includes a shaft portion and a gear portion including a tooth portion, which engages with a tooth portion of the other one of the driving gear and the driven gear, an annular recessed portion is formed at a stepped portion between the gear portion and the shaft portion, the annular recessed portion, and the housing includes a bearing bore having a bearing surface and an annular protruding portion, which is fitted into the annular recessed portion. | 03-11-2010 |
20100242650 | DRIVING FORCE TRANSMITTING DEVICE AND VEHICLE SEAT SLIDE DEVICE - A driving force transmitting device having a direction changing gear mechanism which transmits a rotation torque from a drive shaft to a driven shaft having an axis extending in a direction different from a direction of an axis of the drive shaft. The direction changing gear mechanism includes an output, an input gear attached to the drive shaft for restricting a relative rotation and engaged with the output gear, a gear housing rotatably supporting the output gear and the input gear under engagement condition, wherein one of the output gear and the input gear is provided with a rotation phase adjusting portion exposed outside for adjusting a rotation phase of the output gear relative to a rotation phase of the second engagement portion of the driven shaft upon the output gear being assembled to the driven shaft. | 09-30-2010 |
20100288903 | SCREW CONFIGURATION OF SEAT APPARATUS FOR VEHICLE - A screw configuration of a seat apparatus for a vehicle includes a screw member axially rotatably supported at one of a lower rail adapted to be mounted on a floor of the vehicle and an upper rail slidably supported at the lower rail and adapted to support a seat for the vehicle, extending in a sliding direction of the upper rail, including a protruding portion configured by two raised portions formed to be raised at an outer circumferential surface of the screw member from both sides in an axial direction of the screw member by cold rolling so as to be coupled and to contact each other, and positioned in the axial direction of the screw member by means of the protruding portion, and a transmitting nut member fixed to the other one of the lower rail and the upper rail so that the screw member is screwed there through. | 11-18-2010 |
20130328372 | VEHICLE LOCK - The present invention provides a lock device for locking by inserting a striker into a base member. The lock device includes a latch, which is disposed on the base member and constrains and releases the striker, and a pawl, which holds the latch. Backlash of the latch is limited by a simple structure. A cam member is rotationally connected to the base member by a rotation shaft different from that of the pawl. An engaging protrusion and recess are formed on the pawl and cam member, respectively. When the pawl is at an allowable position, the protrusion and recess are engaged with each other to hold the cam member. The engagement is released when the pawl rotates to a holding position, engaging the cam member with the latch, which is at a locked position, thereby rotating the latch such that the striker contacts the bottom surface of a base groove. | 12-12-2013 |
