A vehicle seat apparatus includes a vehicle seat; a swiveling drive unit that swivels the vehicle seat between a frontward-oriented position in which the vehicle seat faces the front of a vehicle and at least one of an outward-oriented position in which the vehicle seat is oriented in the outward direction of the vehicle and an inward-oriented position in which the vehicle seat is oriented in the inward direction of the vehicle; an occupant condition detection unit that detects the condition of an occupant in the vehicle; and a control unit that controls the swiveling drive unit based on the detection result obtained by the occupant condition detection unit. With this configuration, it is possible to further increase the comfort of a passenger compartment based on the condition of the occupants in the vehicle.

With a vehicle seat arranging structure, a second-row passenger-side seat may be placed in a rearward slide position by sliding the second-row passenger-side seat toward the rear of a vehicle by 150 millimeters so that the second-row passenger-side seat is closer to the rear of the vehicle than the second-row driver-side seat. In addition, each of the second-row driver-side seat and the second-row passenger-side seat may be placed in an obliquely-inward frontward-oriented position by swiveling each of the second-row driver-side seat and the second-row passenger-side seat from the frontward-oriented position 10 degrees inward in the vehicle-width direction. In this way, the sense of distance between the occupants seated in the second-row driver-side seat and the second-row passenger-side seat is reduced. As a result, it is possible to promote communication between these occupants (to make it easier for these occupants to communicate with each other).

A vehicle seat is taught that preferably include a seat cushion (10), a seat back (20) rotatably connected to the seat cushion via a reclining mechanism (30), front (40) and rear (46) legs removably connecting the seat cushion to a vehicle floor (66), a retracting link (50), an operating member capable of removing the front and rear legs from the floor, and a coupling link (54). The seat back can be rotated forwardly by unlocking the reclining mechanism, so as to be superimposed on the seat cushion. When the front and rear legs are removed from the floor, the seat can be moved from a use condition to a retracted condition depending on the motion of the retracting link. When the seat is moved from the use condition to the retracted condition, the coupling link rotates the front leg based on a displacement of the retracting link, thereby unlocking the reclining mechanism

In an automobile having a seat cushion supporting the hip, and a seat back supporting the back, of a seated person wherein the seat back in its use position with the seat cushion folded thereon is lifted up to its non-use position in an upper part of the cabin, the seat back when moved from the use position to the non-use position is prevented from interfering with a seat disposed in its front. There is a guide means for guiding the seat back 12 so that it moves rearwards gradually when it is moved from the use position to the non-use position.

In an automobile having a seat cushion 13 and a seat back 12 to be stored in an upper part of a vehicle interior, the seat cushion 13 and the seat back 12 can be lifted easily to the upper part position of the vehicle interior. The seat cushion 13 is rotatably coupled to the seat back 12 so that the seat cushion 13 can be superposed on the seat back 12, the seat back 12 is supported on a vehicle body 1 so that the superposed seat cushion 13 and seat back 12 can be rotated to the upper part of the vehicle interior, and a rear surface 12B of the seat back 12 is provided with a handle arm 16 that is grabbed by an operator to lift up the seat back 12 and the seat cushion 13 to the upper part of the vehicle interior.

A protecting cover and a pickup device, each having a hooking portion, are rotatably provided at the flank of an image forming apparatus. The rotational centers of the protecting cover and the pickup device and the hooking portions are arranged in such geometry that the hooking portions become engaged with each other only in the range from a predetermined trace intersection to the flank of the image forming apparatus when the protecting cover is rotated from its usage position toward its retracted position at the flank of the image forming apparatus. The pickup device is stopped at the starting position of engagement where the hooking portions are positioned at the trace intersection when sheet feed is not made, and is moved to the operating position when sheet feed is to be made. The protecting cover is constructed so as to rotate in linkage with the rotation of a paper feed tray which is rotatably provided at the flank of the image forming apparatus.
摘要:
A sheet transport apparatus of the present invention is arranged so that a first eject tray is located at a position to which sheets are ejectable in such a manner that front and back surfaces of the sheets are not reversed after the sheets are subjected to predetermined processing. Further, the sheet transport apparatus of the present invention is provided with a first eject tray operation section for aligning leading edges of the sheets ejected to the first eject tray by changing a positional relation in a vertical direction between an upstream side and a downstream side of the first eject tray in a sheet transporting direction.
摘要:
A weight detector for detecting the weight of a passenger seated on a vehicle seat includes a first load sensor and a second load sensor provided on opposite sides of a rear portion of the vehicle seat. Each of the first and second load sensors has a predetermined detection range. The weight detector further includes a third load sensor and a fourth load sensor provided on opposite sides of a front portion of the vehicle seat. Each of the third and fourth load sensors has a predetermined detection range. If a detection value based on a load acquired by one of the first through fourth load sensors exceeds its detection range, the weight detector uses an old value that was determined under proper condition. Otherwise, the weight detector determines the size of the passenger based on the currently detected values.
