摘要： A neck injury is improved with a structure having a lifting mechanism part only on one side. While a lifting driving part (160) is provided on a side of one side frame (11), a coupling driving rod (170) is coupled to a rotation center of a drive gear (160d), a driving link (171) is disposed on a side of the other side frame (11), and the driving link (171) is coupled to the coupling driving rod (170). A driving force in the lifting driving part (160) operates on the side of one side frame (11) having the drive gear (160d), but on the side of the other side frame (11), the driving link (171) rotates together with the drive gear (160d) via the coupling driving rod (170), so as to perform a lifting or lowering operation. The shape of a virtual square coupling contact points of the driving link (171), the side connectors (153, 153), the coupling driving rod (170), and the drive gear (160d) does not collapse, and thus an external input is dispersed.

摘要： The present invention more reliably suppresses output-side displacement than conventional mechanisms. The present invention is provided with a rotation control unit 120 that maintains a locked state when an input torque rotating a transfer mechanism 110 is not applied, and releases the locked state when the transfer mechanism 110 rotates. The rotation control unit 120 has an internal gear 124 and lock plates 123 that include outer teeth that can engage with inner teeth of the internal gear 124. When an input torque is not applied, the inner teeth of the internal gear 124 engage with the outer teeth of the lock plates 123, and when the transfer mechanism 110 is rotated, engagement between the inner teeth and the outer teeth is released. Thus, even when torque is applied from the output unit side, engagement between the inner teeth and the outer teeth is not released by the torque.
摘要翻译：与传统机构相比，本发明更可靠地抑制了输出侧位移。本发明设置有旋转控制单元120，该旋转控制单元120在未施加旋转传送机构110的输入扭矩时保持锁定状态，并且当传送机构110旋转时释放锁定状态。旋转控制单元120具有内齿轮124和锁定板123，锁定板123包括能够与内齿轮124的内齿啮合的外齿。当没有施加输入扭矩时，内齿轮124的内齿与外齿锁定板123的齿，并且当传送机构110旋转时，内齿与外齿之间的接合被解除。因此，即使当从输出单元侧施加扭矩时，内齿与外齿之间的接合也不会被扭矩释放。

摘要： A second member is rotated with respect to a first member more smoothly than in conventional structures. The present invention has a worm 50, and a main driving side worm wheel 40 and a driven side worm wheel 60 which are disposed across the worm 50. Both end portions of the worm 50 in an axial direction are axially supported by bearing parts. In a direction substantially orthogonal to an axial center of the worm 50, respective teeth of the main driving side worm wheel 40 and the driven side worm wheel 60 contact both sides of the worm in the direction substantially orthogonal to the axial center with a backlash, and are supported thereby. When the second member is relatively rotated with respect to the first member, the worm 50 rotates relatively with respect to the main driving side worm wheel 40. The driven side worm wheel 60 rotates by a rotational force of the worm 50, and a rotational force of the driven side worm wheel 60 is regenerated in the worm 50. Whirling vibrations of the worm 50 are suppressed, and relative rotation is performed smoothly.

摘要： A structure in which two worm wheels are disposed across a worm provides an increase in locking reliability while maintaining stable operation during rotation. At the time of rotation, respective rotating fulcrums set at both end portions in an axial direction of a worm 50 are supported by bearing parts 510, 520. At the time of locking, a locking fulcrum set at an eccentric position on one end portion in the axial direction of the worm 50 is supported by one bearing part 510, while on the other end portion in the axial direction, the rotating fulcrum is supported by the other bearing part 520 as is. As a result, the angle of lead of the worm supported by the pair of bearing parts 510, 520 is changed between the time of rotation and the time of locking and becomes smaller at the time of locking than at the time of rotation, whereby an increase in locking reliability can be achieved.

摘要： To provide a seat support mechanism that is provided with a lifter, as well as is able to perform a cushion frame suspension function no matter to what height a cushion frame is adjusted. Torsion bars 330, 340 extending in the width direction of a cushion frame 10 and elastically supporting the cushion frame 10 are supported by a link mechanism 40 disposed between sliders 20 and the cushion frame 10. Even if the attitude of the link mechanism 40 is displaced when the lifter 30 adjusts the height, the positions of the torsion bars 330, 340 are displaced so as to follow the displacement. The torsion bars 330, 340 elastically support the cushion frame 10 no matter to what height the torsion bars are displaced. Thus, no matter to what height the cushion frame 10 is adjusted, the torsion bars 330, 340 are able to support the cushion frame 10 with predetermined elasticity and to exhibit predetermined vibration absorption characteristics.
