Problems solved by technology

On the other hand, when a force to rotate the inner cylinder is applied from the pinion gear on the output side, each brake spring acts in the direction of expanding the diameter, and the inner cylinder cannot rotate due to contact with the inner peripheral surface of the outer cylinder.

Embodiment Construction

[0032] Hereinafter, the present invention will be described in further detail based on the illustrated embodiment.

[0033] figure 1 The seat cushion frame 3 having the lifting mechanism 2 in which the rotational force transmission control mechanism 1 of one embodiment of the present invention is assembled is shown. The cushion frame 3 is supported by the upper rails 42 and 42 of the pair of sliders 4 and 4. The lifting mechanism 2 has front links 21, 21 and rear links 22, 22 arranged between the upper rails 42, 42 and the side frames 31, 31 constituting the seat cushion frame 3, and has an opposite side to the upper rail 42, 42 The scroll spring 5 that urges the seat cushion frame 3 (side frames 31 and 31) upward is configured to include the rotational force transmission control mechanism 1 of this embodiment.

[0034] Such as Figure 2 ~ Figure 4 As shown, the rotational force transmission control mechanism 1 is configured to include a feeding mechanism 110, a rotation control ...

Abstract

The present invention more reliably suppresses output-side displacement in comparison with conventional mechanisms. The present invention is provided with a rotation control part 120 which maintains a locked state when an input torque rotating the transfer mechanism 110 is not applied, and which releases the locked state when the transfer mechanism is rotated. The rotation control part 120 has an internal gear 124 and a lock plate 123 which has outer teeth that can be engaged with internal teeth of the internal gear 124. When an input torque is not applied, the inner teeth of the internal gear 124 are engaged with the outer teeth of the lock plate 123, and when the transfer mechanism 110 is rotated, the engagement of both the internal and outer teeth is released. Thus, even if torque is applied from the output side, the engagement of both the internal and outer teeth is not released by the torque.

Description

Technical field [0001] The present invention relates to a rotational force transmission control mechanism and a seat structure provided with the rotational force transmission control mechanism. Background technique [0002] For example, as shown in Patent Document 1, as the lifting mechanism of the seat structure, the following mechanism is known: In the feed mechanism (in Patent Document 1, it is configured to include an operating handle, a handle base, a locking base, a locked member, and an operating When the shaft mechanism is rotated from the neutral position due to the input torque, the output part rotates to rotate the pinion gear and the sector gear connected to the output part to raise and lower the seat cushion. [0003] In Patent Document 1, a brake drum for controlling the transmission of input torque to the output unit is interposed between the feed mechanism and the output unit. The brake drum has an outer cylinder and an inner cylinder (in Patent Document 1, the inn...
