摘要： A structural unit having a net member incorporated therein capable of preventing local application of undue force to the net member, to thereby increase reliability of the net member. An end section of a net member of a three-dimensional structure is treated so as to be reduced in cushioning characteristics and increased in hardness as compared with a portion of the net member positioned inside the end section. A frame constituting a part of the structural unit is provided with an end holding member so that an insertion port of an insertion gap of the end holding member is arranged in a particular direction or posture, resulting in the end section being readily held in the holding member by merely inserting the end section in the insertion gap. The end section is entirely inserted into the insertion gap, so that application of load to the end section may be carried out in a two-dimensional manner rather than a spot-like manner. This prevents local application of load to the net member, to thereby keep the net member from damage thereto.

摘要： A seat in which a cushioning member has a high following ability to a human body motion and which can efficiently damp a vibration inputted from the outside is provided. The seat is constituted to use a torsion bar 112 and to support a cushioning member of a seat cushion section 150 by a parallel link mechanism having a first link plate 113 pivotally supported by the torsion bar 112, a second link plate 116 disposed in correspondence with the first link plate 113, and a connection link plate 117 connecting the first link plate 113 and the second link plate 116, and operational directions of the first link plate 113 and the second link plate 116 are set to almost coincide with a vertical direction along a surface of a seat back section. Thus, a rotational motion following a human body motion generated by an external vibration input is performed, so that a relative motion between a human body and the cushioning member is small and a resonance peak is lowered, whereby a vibration absorption characteristic can be improved.

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： To expand a body weight adjustment range and achieve thinning. An initial position adjusting member 15 which can adjust initial resilient forces of two torsion bars 31, 41 is provided. Therefore, a body weight adjustment range is expanded as compared with a conventional configuration where a resilient force of only one torsion bar is adjusted. Since a moving magnet unit 52 is provided such that a moving direction of a moving body coincides with an approximately perpendicular direction to a mutual displacement direction of an upper frame 10 relative to a lower frame 20, the thickness (height) of a fixed magnet unit 51 is made thin as compared with a case where the moving magnet unit is provided such that the moving direction of the moving body coincides with approximately the same direction as the mutual displacement direction of the upper frame relative to the lower frame, so that the thickness of the whole seat suspension at a position at which the upper frame 10 has come closest to the lower frame 20 (a lower limit position) can be made thin.

摘要： Follow-up performance to respiratory movements is made higher than that of the prior art without obstructing movements of the pelvis of a person. A configuration is adopted that a cushioning member arrangement frame for a seat back 34, 140 and a cushioning member arrangement frame for a seat cushion are displaced according to load fluctuation to a cushioning member for a seat back 40, 150 or a cushioning member for a seat cushion 20. That is, such a configuration is adopted that the cushioning member arrangement frame for a seat back 34, 140 or the cushioning member for a seat cushion 20 not only moves according to load fluctuation but also frames themselves supporting them move via tension structure members spread over the frames (a cushioning member for a seat back and a cushioning member for a seat cushion). Accordingly, when a person lays his/her pelvis at his/her sitting position for deep breathing, the cushioning member arrangement frame for a seat back is displaced to push the vicinity of an upper portion of the cushioning member for a seat back, so that the vicinity of a lower portion of the cushioning member for a seat back is pushed forward to enrich support of the sacrum of the person.

摘要： A vibration damping apparatus using a magnetic circuit which is easier and less expensive to manufacture than conventional apparatus is provided. The apparatus comprises a moving member 30 placed to move relatively away from and close to magnets 20 and 21 and made of a magnetic material which generates attraction force between the moving member 30 and the magnets 20 and 21, metal springs 40 and 41 as elastic members urging the moving member 30 in a direction in which the moving member 30 approaches the magnets 20 and 21, and rubbers 60 and 61 as cushioning members mounted on predetermined positions to prevent the moving member 30 from coming in contact with the magnets 20 and 21. A negative spring constant is created by using an attracting magnetic circuit formed between the magnets 20 and 21 and the moving member 30, and to this, the elastic force of the metal springs 40 and 41 having a positive spring constant with the same value as the negative spring constant is added, whereby a total spring constant within a predetermined range of displacement can be set to substantially near zero by a very simple configuration.

摘要： The object of the present invention is to improve the production efficiency by making its bonding process unnecessary to simplify the production process. The method of production comprises the step of integrally incorporating a magnetic material when the stationary holders 21 and 22 of the stationary member and the movable holder 31 of the movable member 30 are molded with a non-magnetic material such as a plastic material and the like. Therefore, a magnet unit in which the stationary magnets 23 and 24 or the movable magnet 32 is integrally incorporated into the stationary holders 21 and 22 or the movable holder 31 can be provided only by giving magnetization treatment on the magnetic material without using a bonding process.
