摘要： To enable an output sound of a speaker unit to be output as a surface sound source in a limited space. A three-dimensional knitted fabric is provided at a position substantially facing speaker units while being given tension in a surface direction. Since the tension is applied, a pair of ground knitted fabrics constituting the three-dimensional knitted fabric and a connecting yarn extending back and forth between the ground knitted fabrics vibrate due to their elastic action. In particular, string vibration is generated in the connecting yarn. Due to this vibration, output sounds of the speaker units are propagated in the surface direction of the three-dimensional knitted fabric, and as a result, the three-dimensional knitted fabric propagates and radiates acoustic waves of a surface sound source.

摘要： A rotating movement control mechanism including a worm, and a main driving side worm wheel and a driven side worm wheel disposed across the worm. Both end portions of the worm in an axial direction are axially supported by bearing parts. Respective teeth of the main driving side worm wheel and the driven side worm wheel contact both sides of the worm in a 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 rotates relatively with respect to the main driving side worm wheel. The driven side worm wheel rotates by a rotational force of the worm, and a rotational force of the driven side worm wheel is regenerated in the worm. Whirling vibrations of the worm are suppressed, and relative rotation is performed smoothly.

摘要： In order to improve vibration absorbency and impact absorbency, the seat structure includes a swing member provided in a manner to be able to swing at least back and forth on a rear frame member positioned around the rear of a seat cushion, a pelvis supporting member connected to the swing member at the vicinity of the lower portion of the pelvis supporting member and disposed behind the pelvis of a seated person, and coil springs as an elastic member to support the pelvis supporting member biasing in the direction pushing forwards in a normal seating state. Accordingly, vibration inputted from the seat back side and as if patting on the back of the human body can be absorbed by the pelvis supporting member supported elastically. Besides, since the pelvis supporting member is connected to the rear frame member via the swing member, since pivoting movement in the back-and-forth direction of the pelvis supporting member is performed with a connecting portion of the swing member and the rear frame member as the center, and the radius of gyration is large, the vicinity of the lower portion of the pelvis supporting member never presses the pelvis.
摘要翻译：为了提高振动吸收性和冲击吸收性，座椅结构包括摆动构件，其以能够至少在位于座垫的后部的后框架构件上来回摆动的方式设置，骨架支撑构件连接到骨盆支撑构件的下部附近的摆动构件，并且设置在就座人的骨盆后面，螺旋弹簧作为弹性构件，以支撑骨盆支撑构件在正常就座状态下向前推动的方向。因此，从座椅靠背侧输入的振动和仿佛拍摄在人体背部的振动可以被弹性支撑的骨盆支撑构件吸收。此外，由于骨盆支撑构件经由摆动构件连接到后框架构件，因此通过摆动构件和后框架构件的连接部分进行骨盆支撑构件的前后方向的枢转运动作为中心，并且回转半径大，骨盆支撑构件的下部附近从不压迫骨盆。

摘要： The object of the present invention is to provide a vibration damping apparatus having 6 degrees of freedom using a magnetic circuit. Vibration transfer can be isolated by a vibration damping mechanism to set the spring constant utilizing a relative displacement of a movable magnet 37 to a stationary magnet 27 in an axial direction, and an elastic force of a metal spring 50 substantially to be zero. The displacement is quickly restored to an original position by a rubber 24a and the metal spring 50 composing a device to restore the displacement due to vibration not only in an axial direction (Z axis direction) but also in a horizontal direction (X or Y axis direction), in a rotational direction around each axis, or in a twisting direction which is an overlapping direction of these directions and is damped as a vibration in an axial direction. Accordingly, a vibration having 6 degrees of freedom can be controlled with a simple structure.

摘要： An upper end portion of a seat backrest and a lower end portion of a head rest are superposed together. A rear end portion of an upper portion cushion member and a lower end portion of the seat backrest are superposed together. These superposed portions are sewn together by thin threads which break when pressing force of a predetermined value or greater is applied to the seat backrest. Thus, when pressing force of the predetermined value or greater is applied to the seat backrest, the thin threads break. A portion of the seat backrest which a shoulder portion of a seated occupant contacts, and a portion of the seat backrest which buttocks of the seated occupant contact, are enlarged, and impact force can be damped.

摘要： The object of the present invention is to suppress rebound of a human body when receiving a large impact load accompanying a collision or the like. A back frame member 20 and a seat frame member 10 are individually formed by welding or caulking, and a link member 30 for connecting both is attached to the back frame member 20 and the seat frame member 10 by welding or caulking. Each of the frame members is provided with a cushioning member as a tension structure. Upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the tension of the cushioning member provided as the tension structure lowers to be able to exhibit high damping characteristics.

摘要： Blood pressure is estimated in a non-constraining manner continuously and in real time. A biological signal collected from a person's dorsal part is analyzed, vibration in the human body ascribable to a blood flow rate change in a period from the ventricular filling period to the isovolumetric systole is captured, and the state of fluctuation of an index indicating the state of the in vivo vibration is further captured. This fluctuation index correlates with a person's blood pressure. Therefore, it is possible to estimate whether the blood pressure is in a range indicating a normal-range blood pressure or in a range indicating a high blood pressure, only by having the person sit or lie supine on a surface provided with a biological signal measurement device to measure a biological signal in a non-constraining manner, so as to make the biological signal measurement device contiguous with the person's dorsal part.
