Description

  The present invention relates to a vehicle seat device including a slide device that operates up and down movement in and out of a vehicle when the seat is rotated laterally outside the vehicle.

  Conventionally, in a vehicle seat device that has a function of rotating the seat forward and laterally outside the vehicle and also has a function of moving the seat outside the vehicle when it is laterally outside the vehicle, the vehicle seat device also moves downward when moving outside the vehicle. It is common to move and descend to a height that is easy to sit on. Various structures have been proposed for lowering while moving to the outside of the passenger compartment, but the structure becomes complicated and hinders cost reduction in order to secure the lifting stroke and to control the posture of the seat during lifting It has become. In addition, since a large thrust / holding force is required when moving up and down, there are many structures in which a ball screw or trapezoidal screw is rotated with an electric motor to move the mating nut back and forth, but this structure is expensive and the operation noise is high. There was a problem of being big.

  In Patent Document 1, a slide mechanism having a rail fixed on a base member in a vehicle interior and a moving body having a moving element that horizontally moves along the rail, a base end is a moving body, and a front end is a seat body. And a four-joint link mechanism composed of two link arms connected to each other. When the moving body moves forward and backward along the rail, the link arm is rotated by the guide mechanism to rotate the seat body. In the vehicular seat elevating device for lowering and raising, the moving body includes a front moving element 62 and a rear moving element 60, and the front moving element 62 is engaged with the rail 42 so as not to move upward. In this state, a configuration has been proposed in which the slider moves horizontally along the rail 42 and the rear moving element 60 moves horizontally while rolling on the upper surface 42b of the rail.

  Patent Document 2 discloses a vehicle seat moving device that can move at least a part of a seat to the outside of a vehicle from an opening of the vehicle, and a base member that is installed on a vehicle body, and can be moved forward and backward with respect to the base member. A first slide member that is held, a first drive actuator that moves the first slide member forward and backward with respect to the base member, and an intermediate that is pivotally supported by the first slide member so that the vicinity of the rear end portion can swing.

  The basic configuration of the invention disclosed in Patent Document 1 includes a front / rear slide mechanism 20 that slides in the front-rear direction of the seat body 10, a rotation mechanism 30 that horizontally rotates the seat body 10 within a range of 90 degrees, and a door opening of the seat body 10. The four-link mechanism elevating mechanism 80 that moves to the height close to the road surface while moving to the outside of the passenger compartment through the portion K, and the second slide mechanism 50 that moves the seat body 10 horizontally independently of the elevating mechanism 80 downward It was bulky in the height direction because it was laminated from top to bottom. Further, the riding comfort during operation in which the front / rear slide mechanism 20 and the second slide mechanism 50 slide on the rail is completely different from the riding comfort during operation in which the lifting mechanism 80 of the four-bar linkage mechanism moves up and down with the middle point of the link as a fulcrum. However, it changed intermittently.

  Since Patent Document 2 is configured such that an intermediate frame and a seat frame are slidably and swingably stacked on a base member so as to be able to advance and retreat, the same as Patent Document 1, it is bulky in the height direction. It was a thing. Further, the intermediate frame is supported by a first guide member having a guide cam surface with respect to the base member, and the seat frame is supported by a second guide member having a guide groove so as to be swingable with respect to the intermediate frame. Therefore, the seat is likely to swing during elevation.

  The vehicular seat device of the present invention has been devised to solve such a conventional problem and to provide a vehicular seat device that has a simple structure, reduces manufacturing costs, and has a quiet operation sound and is comfortable.

  A rotating plate assembly, a lower slide assembly, an upper drive slide assembly, and an upper slide assembly comprising an upper driven slide assembly are stacked in this order, and the rotary plate assembly is mounted on a base frame supported in the vehicle interior of the vehicle. In a vehicle seat device that is rotatably supported in a vehicle forward direction and a vehicle lateral direction, a rotary plate assembly in which a lower guide rail outer is provided on both sides of a front end guide roller is provided on a front end portion. The lower guide rail inner and outer lower guide rail outer and inner inwardly facing lower and outer guide rail inners are integrally provided on both sides, and the lower rear guide roller on the side of the rear end of the outer lower guide rail inner. The front guide roller on the side of the front end protrudes outward and protrudes outward on the inner side of the lower guide rail. The upper slide guide assembly is provided with an upper front guide roller at the front end and an upper rear guide roller at the rear end on both sides of the lower slide assembly and the upper drive slide assembly portion, respectively. An inward upper guide rail outer in which a rear end portion and the upper drive slide assembly portion are rotatably connected, and both sides are set to be inclined downwardly from the lower guide rail inner of the lower slide assembly. An upper slide reciprocating mechanism is provided for the upper slide assembly, and the upper slide reciprocating mechanism is provided for the lower slide assembly and the rotating plate assembly. The vehicle seat apparatus is provided with a mechanism.

  The lower rear guide roller of the lower slide assembly rolls in the lower guide rail outer of the rotary plate assembly, and the lower front guide roller of the rotary plate assembly rolls in the lower guide rail inner of the lower slide assembly, respectively. The lower slide assembly may be arranged so as to be supported by the lower guide rail outer of the rotating plate assembly so as to perform a slide operation.

  The upper front guide roller and the upper rear guide roller of the upper drive slide assembly are arranged so as to be able to roll in the lower guide rail outer of the lower slide assembly, and this upper drive slide assembly is arranged on the lower guide rail outer. It may be configured to be provided so as to be supported by the sliding operation.

  A rotatable angle is provided on the upper rear guide roller support shaft of the upper drive slide assembly part, and this angle is configured to be integrally coupled to the rear end part of the upper driven slide assembly part. Is also good.

  The upper front guide roller is rotatably provided in the upper guide rail outer provided on both side surfaces of the upper driven slide assembly, and the upper driven slide assembly is provided as an upper drive slide assembly. It may be configured such that it is arranged so as to be slidable forward and downwardly inclined with respect to the lower guide rail inner by rotating about the upper rear guide roller support shaft.

  The lower slide assembly may be configured to be slid by a lower stage reciprocating mechanism using a pinion gear rotated by a motor supported by the lower slide assembly and a rack gear supported by the rotary plate assembly with respect to the rotary plate assembly. It ’s good.

  The upper drive slide assembly of the upper slide assembly is reciprocally operated by a pinion gear rotated by a motor supported by the upper drive slide assembly and a rack gear supported by the lower slide assembly relative to the lower slide assembly. It may be configured to be slid by a mechanism.

  In the vehicle seat device according to the present invention, since the slide mechanism is configured as described above, the pitch of the guide rollers supported as the retracted slide is increased in both the slide of the lower slide assembly and the slide of the upper slide assembly. Since it expands, an unnecessary moment is not applied, and the seat can be lifted and lowered stably.

  Since there is no connection between the guide roll and the rail, there is no operation shock and the riding comfort is good. In addition, the driven slide assembly portion of the upper slide assembly is tilted so that the front end portion of the seat is lowered with the rear end portion as a fulcrum while sliding forward and downward in the slide, so that the boarding / exiting performance is improved.

  The slide of the lower slide assembly and the upper slide assembly are configured not to be stacked but to wrap in the horizontal direction, so that they can be made thin. And the seat surface height of a rotation raising / lowering slide seat can be made low, and it is advantageous to the entrance / exit of the entrance / exit.

  Since the combination of each part is a combination of a rail and a guide roller and the structure is simple, the manufacturing cost can be reduced.

  By adopting a rack and pinion for driving an inclined slide that requires a large thrust and setting a reduction gear outside the motor, it is possible to use a small-sized motor that can be mass-produced, thereby reducing costs.

  Since a small motor is used, it is possible to achieve both quiet operation noise and reduction in manufacturing cost.

  Unlike PWM (Pulse Wide Module) control, etc. where the torque drops when the two-stage slide is single-acting → overlapped → single-actuated and decelerated, low-speed operation (rotating plate) while maintaining stable torque Single slide of lower slide assembly relative to assembly) → High speed operation (slide of lower slide assembly relative to rotating plate assembly and double slide operation of upper slide assembly relative to lower slide assembly) → Low speed operation (upper stage relative to lower slide assembly) It is possible to reduce the shock at the start of the slide and at the completion of the slide.
