摘要： A magnetic spring has at least two permanent magnets (2 and 4) spaced from each other in a kinetic mechanism. At the time of input and at the time of output, the geometric dimensions between the two permanent magnets are changed by the kinetic mechanism or an external force. The change in geometric dimensions is converted into a repulsive force in the kinetic mechanism, thereby (1) making the repulsive force from a balanced position of the two permanent magnets greater at the time of output than at the time of input, or (2) deriving a damping term of the magnetic spring to provide nonlinear damping and spring characteristics.

摘要： A motion sickness expression apparatus capable of causing expression of motion sickness on a person riding in any posture on the apparatus without setting the apparatus in a vehicle. The apparatus includes a base, a vertical vibrator to which the vibration application unit is connected so as to be vertically movable with respect to the base through link members and which is constructed so as to support the body carrying section thereon, and a magnetic spring mechanism including permanent magnets arranged on the base and vertical vibrator so as to repel each other, respectively. The magnetic spring mechanism also includes an actuator for moving the permanent magnet arranged on the base to vary areas of the permanent magnets opposite to each other, leading to vibration of the vertical vibrator. Vibration of the body carrying section can be controlled through the vertical vibrator vibrated by repulsion force of the permanent magnet on the vertical vibrator with respect to the permanent magnet on the base due to driving of the actuator so that an acceleration of vibration of the body carrying section falls within a motion sickness expression region.

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： A cushion member includes an intermediate layer, and an upper layer and lower layer stacked and fixed thereto. The cushion member is fixed to a frame by bending an end part of the cushion member so that the upper layer comes to the front side and the lower layer comes to the back side. The intermediate layer is subjected to shear force and the upper layer and the lower layer are subjected to compressive and tensile stress. With the spring characteristic of the intermediate layer, residual stress of the tension and compression is applied to the upper and lower layers from the intermediate layer. Thus, the cushion member can have a restoring property, generation of creases during no load application can be reduced, permanent setting is made less likely, and a compression characteristic in the thickness direction is increased.
摘要翻译：缓冲构件包括中间层，以及堆叠并固定在其上的上层和下层。缓冲构件通过弯曲缓冲构件的端部而固定到框架，使得上层进入前侧，下层到达后侧。中间层承受剪切力，上层和下层受到压缩和拉伸应力。随着中间层的弹簧特性，拉伸和压缩的残余应力从中间层施加到上层和下层。因此，缓冲构件可以具有恢复特性，可以减少无负荷施加期间的折痕的产生，使永久性设定变得不太可能，并且厚度方向上的压缩特性增加。

摘要： A seat includes a seat cushion frame, a seat back frame mounted to the seat cushion frame, and at least one three-dimensional net having upper and lower mesh layers and a pile layer made up of a large number of piles for connecting the upper and lower mesh layers. The three-dimensional net is stretched over substantially the entire region of the seat cushion frame and the seat back frame, thereby forming a seat cushion and a seat back. The three-dimensional net has a fixed end at a front end portion of the seat cushion and another fixed end at an upper end portion of the seat back. The seat also includes a first tension member attached to the three-dimensional net at a location adjacent to a central portion thereof for imparting tension thereto, and a second tension member attached to another portion of the three-dimensional net for fastening it to at least one of the seat cushion frame and the seat back frame.

摘要： A cushion structure that does not cause pain to a user when seated and that promotes steady breathing. Three dimensional knit fabrics are formed as a laminate of plural stacked layers, and a minimal-layer structure section, which does not possess at least even a single intermediate layer between the topmost layer and the bottommost layer, is provided on the approximate center section in the width direction in a prescribed width and in a prescribed length from front to back. The approximate center section in the width direction of the cushion structure is the region upon which the area around the sacrum is positioned when the user is seated.

摘要： A seat includes a seat frame, and a cushion material supported by the seat frame and having a three-dimensional knitted fabric which is formed by joining, with connecting threads, a pair of ground knit fabrics which are disposed so as to be separated from one another. The cushion material includes a first region whose elastic compliance when a reaction force is applied to an extending side of the cushion material when an occupant is seated on the seat is substantially equivalent to an elastic compliance of a portion of the occupant's body pressing the cushion material and a second region whose elastic compliance is larger than that of the first region. Accordingly, a thin and light seat can be provided, load concentration on the occupant's tuber ishiadicum bottom portion when seated for a long period of time can be mitigated, and vibration-transmitting characteristics can be improved.
