A body weight adjustment mechanism for automatic adjustment to a balanced point is provided to improve vibration absorption characteristics and impact absorption characteristics. A torsion angle of a lower frame-side torsion bar when an upper frame is at a balanced point is found in advance, a torsion angle of the lower frame-side torsion bar in a state in which a person is seated is detected, the detected torsion angle is compared with the aforesaid balanced point torsion angle, a control signal is sent to an elastic force adjusting unit, and torsion angles of upper frame-side torsion bars are adjusted so that the torsion angle of the lower frame-side torsion bar becomes equal to the balanced point torsion angle. The upper frame can be set to an appropriate position in an initial state and a static state in which a person is seated and vibration and impact absorption characteristics are improved.

To increase strength without any weight increase due to a thickness increase and without causing the machining problem in half-blanking, an external gear and an internal gear are ring-shaped gears, and external teeth and internal teeth each have a tooth width substantially corresponding to the thickness of an outer circumferential surface of the external gear or an inner circumferential surface of the internal gear. The external gear and the internal gear are ring-shaped gears, that is, each can be formed through the punching of a plate, and strength resulting from the engagement of the external teeth and the internal teeth corresponds to strength resulting from the thickness of the material plates forming the external gear and the internal gear. Accordingly, the external teeth and the internal teeth can have a wider tooth width, achieving higher strength than when half-blanking is used.

A damper is provided on an upper frame which is a main vibrating body supported on upper portions of front links and rear links of a frame link mechanism, so as to be a sub-vibrating body which generates vibration whose behavior is different from that of vibration of the upper frame caused by the rotary motion of the front links and the rear links. When the upper frame is vibrated by input vibration, since the damper exhibits the different vibration behavior, energy of the input vibration not only is distributed as vibrational energy of the upper frame and heat energy generated by the elongation and contraction of the damper but also is consumed as energy which vibrates the damper itself provided as the vibrating body. Such arrangement and configuration of the damper improve basic performance of vibration absorbency and impact absorbency of the suspension and achieves a reduction in thickness.

Provided is a health monitoring device that extracts, in particular, an apical beat component from a trunk acoustic pulse wave and thus is also usable in the medical field. The health monitoring device (1000) of the present invention analyzes a trunk acoustic pulse wave to estimate the health condition of a person using a correlation of an indicator relating to a left ventricular pressure waveform which indicates the behavior of the heart, with a vibration frequency of a frequency component stemming from an apical beat, a diastolic time interval in a cardiac cycle, or blood pressure. The former is input information and the latter is output information of the heart through which blood circulates, and thus comparing these two pieces of information makes it possible to know a health condition relating to the function of the heart more accurately than conventionally.

To reduce a whirling movement and abnormal noise of an output gear part. An input-side shaft part 132 and an output gear part 131 which compose a rotating operation member 130 are integrally formed. Owing to this configuration, a bearing of a feed mechanism is integrated with the output gear part, leading to a reduction in a whirling movement of the output gear part due to axial misalignment. A stepped surface 131a formed on an outer periphery of the rotating operation member 130 is stacked on an outer surface 212a of a peripheral edge part of a gear-part through-hole 212 of an attachment bracket 210, and an elastic member 230 is provided between an inner surface 212b of the peripheral edge part of the gear-part through-hole 212 and a brake mechanism 120. This also reduces a whirling movement of the output gear part 131.

A seat cushion includes a seat cushion base layer which biases two base support parts in directions approaching each other, and has base support part elastic members which are elastically deformed in an up-down direction, thereby causing the seat cushion to have a configuration having a high spring characteristic. In the seat cushion and the seat back, the seat cushion is configured to be set to be larger than the seat back regarding a range of connecting an origin, a maximum displacement point, and a maximum load point, and a ratio of an area of a range including an inward curve to an area of a range including an outward curve in a predetermined load-deflection characteristic.

Wobbling among components is reduced. The seat reclining device includes: outer rolling members (80) disposed between a ring-shaped bottom surface portion (71) of a mounting ring (70) and an outer surface of a guide bracket (20) or an outer surface of an internal gear (30), that faces the ring-shaped bottom surface portion (71); and inner rolling members (90) which are disposed between opposed surfaces of guide groove portions of the guide bracket (20) and lock plates (60A to 60D) to guide the lock plates (60A, 60C) in a radial direction. Owing to the outer rolling members (80) and the inner rolling members (90), force pressing stacked members relatively to one another functions in a stacking direction, and as its reaction force, spring force of the mounting ring (70) acts, so that wobbling is reduced. As for the relative pressing force by the outer rolling members (80) and the inner rolling members (90), the pressing force by the rolling members (80, 90) acts not only in a locked state but also in an unlocked state, so that wobbling among the members is reduced in the both states.
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.

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.
