摘要： In the present invention, a gap 73 is formed between an axial-direction outer end portion of an internal gear 30 and an attachment ring 70, and the gap 73 is filled with a lubricant 74. This configuration makes the rotation of the internal gear 30 relative to the attachment ring 70 smoother and also can reduce the generation of abnormal sound. Further, the thickness of second lock plates 60B, 60D between which and an inner surface of a guide bracket 20 rolling balls 65 are not interposed is equal to or more than the distance between the inner surface of the guide bracket 20 and outer surfaces of first lock plates 60A, 60C, between which the rolling balls 65 are interposed, and preferably substantially equal to the distance. This reduces the precession of the first lock plates 60A, 60C and makes it possible for a load input in an axial direction to be mainly received by the second lock plates 60B, 60D.

摘要： To cause an appropriate damping force to work according to a relative displacement with a simple configuration. A movable inner cylinder 3 slidable in an outer cylinder 2 in an axial direction and having orifices 31 formed in its peripheral wall 31 is provided, a piston 5 around which a linear member 52 that generates a frictional force is wound is further provided in the movable inner cylinder 3, and a viscous liquid 7 is filled in the outer cylinder 2 including the inside of the movable inner cylinder 3. Accordingly, when the piston 5 moves together with the movable inner cylinder 3, a high damping force is not exerted, whereas when the piston 5 relatively moves in the movable inner cylinder 3, the high damping force is exerted owing to viscous friction between the piston 5 and the movable inner cylinder 3 and the viscous resistance of the viscous liquid passing through the orifices.

摘要： To reduce an operation synchronization failure of recliners on both sides of a seat frame, thereby enabling smoother operation despite variations in the dimensional accuracy of the seat frame. A seat recliner structure includes: recliners which are provided on the left and right sides of a cushion frame and a back frame to recline the back frame relative to the cushion frame; and a connecting rod which connects the left and right recliners to synchronize them, wherein the left and right recliners have different backlashes, and the backlash of the driving-side recliner is smaller than the backlash of the driven-side recliner.

摘要： Provided are a seat state switching mechanism which can achieve switching between a walk-in state and a reclining state even with a small number of components, and a seat including the seat state switching mechanism. A seat state switching mechanism is a mechanism which can switch a state of a seatback between a walk-in state and a reclining state, the seat state switching mechanism including: a movable bracket tiltable together with the seatback; a locking member for locking the movable bracket at a predetermined walk-in locking position: and an input member, a first biasing member, and a second biasing member, each composing a releaser, for switching the state of the seatback to the reclining state by releasing a biased state of the locking member in receipt of a reclining operation force.

摘要： Provided is a seat enabling reduction of a burden in skin assembling work and improvement of appearance quality of the seat. A seat includes linear members extending along a longitudinal direction of hanging portions of a skin and provided at the hanging portion, and elastically deformable tubular members provided inside grooves of a pad so as to extend along the groove. A slit is formed on an outer peripheral surface of the tubular member, the slit extending in a longitudinal direction of the tubular member, having a width narrower than an outer diameter of the linear member, and enabling the width to be expanded by elastic deformation of the tubular member.

摘要： An internal gear includes a thin annular portion and a thick annular portion whose outside diameters are the same and whose inside diameters are different are continuously provided integrally in an axial direction, and an outer peripheral surface of the thin annular portion and the thick annular portion is formed in a substantially L shape in a flush cross section. Therefore, a conventionally substantially convex section formed with the memory internal teeth does not become the weak point in terms of strength. An axial outer end surface of the thick annular portion of the internal gear is formed to be substantially flat, and the coupling cover member is fixed to the thick annular portion to be coupled to a frame of a seat cushion or a seat back.

摘要： To provide a power seat slide device having improved effects of reducing abnormal sound, a temperature increase, and so on in gear mechanisms and so on. Gear mechanisms each include a case in which a worm and a worm wheel are rotatably supported, the cases are suspended from and supported by upper rails. The worms are connected to and supported by a rotational force transmission shaft of a drive mechanism, and the worm wheels are screwed to and supported by slide screws provided in lower rails. Further, the cases are supported on the lower rails via balls which are rolling members. This structure stabilizes a slide operation of the cases themselves and can further improve the effects of reducing abnormal sound and so on.

摘要： The present invention uses a time-series waveform of biosignal information collected from the back of a person and including biological sound and vibration (back body surface pulse wave). The back body surface pulse wave is pressure vibration arising from cardiac and aortic motions, and includes ventricular systolic and diastolic information and information on vascular wall elasticity which serves as an auxiliary pump for the circulation, and is considered as a vibration system including both the damping of viscous damping friction and the damping of solid friction. The back body surface pulse wave fluctuates according to a flow rate (stroke volume) of blood pumped out from the heart, and the fluctuation of this flow rate is reflected in the amplitude of the time-series waveform of the back body surface pulse wave. Therefore, by applying a solution which calculates a damping ratio of a free damped vibration waveform to compare predetermined waveform components in one cardiac cycle, preferably, amplitudes of two waveform components in an amplification phase, it is possible to detect a biological state, in particular, a biological state associated with a blood pressure.

摘要： To obtain an integrated foam-molded product whose manufacturing cost is reduced and which makes an effective use of a property of an integration target. Foaming heat generated at the time of the foaming of a polyurethane foam raw material, whose influence has been conventionally prevented by contriving a special measure, is positively used. The integration target is influenced by foaming heat generated at the time of the foaming of the polyurethane foam raw material in a mold, to thermally deform into a desired shape along a mold shape. Consequently, it is possible to mold the integration target into an arbitrary shape in a step of integrating the integration target with a polyurethane foam layer in the mold by integrated foaming, and therefore, there is no need to work the integration target to a state closer to a final shape in a step before it is disposed in the mold, which can simplify manufacturing steps and reduce manufacturing cost.
