摘要： To achieve further weight reduction and thinning of a seat structure. A laminated body obtained by sandwiching a planar member 4 made of cloth between planar members 2 and 3 made of synthetic resin to join them to one another via adhesive agent is used in a shell type frame member of the seat structure. Upon receipt of an impact, delamination is caused between the respective layers configuring the laminated body. Thereby, both the tensile stress and the Izod impact strength of the laminated body are lowered as compared with those of a homogeneous laminated body obtained by joining planer members made of homogeneous materials. That is, impact energy is converted to a force causing delamination between the planar members in the laminated body to be consumed, thereby absorbing the impact energy. Since the shell type frame member itself can absorb the impact, further weight reduction and thinning of the shell type frame member and a seat structure using the same can be achieved.
摘要翻译：为了实现座椅结构的进一步减轻重量和变薄。在座椅结构的壳型框架构件中使用通过将由布合成的平面构件4夹在合成树脂制的平面构件2和3之间而通过粘合剂彼此连接而获得的层叠体。在接收到冲击时，在构成层压体的各层之间引起分层。因此，与通过接合由均质材料制成的平面构件获得的均匀层压体相比，层压体的拉伸应力和艾佐德冲击强度都降低。也就是说，冲击能量被转换为在层叠体中的平面构件之间产生分层以消耗的力，从而吸收冲击能量。由于壳型框架本身可以吸收冲击，因此可以实现壳型框架构件的进一步的减重和变薄以及使用其的座椅结构。

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.

摘要： A seat cushion of a vehicle seat has a base seat whose front end is anchored to a front frame of a frame for a sitting portion, and whose rear end is connected to a rear frame of the frame for a sitting portion via helical tension springs. A supporter, supported via helical tension springs at a pair of left and right side frames of the frame for a sitting portion, is disposed at a lower side of the base seat so as to support a femoral region of a seated person. The supporter and the helical tension springs structure an auxiliary vibration system whose mass element is a femoral region of a seated person. The auxiliary vibration system is made to function as a dynamic vibration absorber with respect to up-down vibrations of a main vibration system whose mass element is an upper body of a seated person.

摘要： There are provided a monitor for monitoring a human condition of a driver, and an awakening device for awakening a driver, which starts operation when received a predictive signal for fall-asleep being a signal for energy metabolism transition from an active state into a sleep state. The awakening device is structured to stimulate a pressure sense of the driver by reclining a seat back of a driver seat forward or rearward to thereby cause a shift force. Accordingly, without regard to an alarm reaction level to an alarm sound, it is possible to stimulate the driver and whereby awaken the driver more surely.

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.

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： 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 structure which can ameliorate fatigue of a sitting person in accordance with a long period of sitting is provided.In a vehicle seat 10, a back edge side of a lower layer sheet 50 of a cushion material 20, of which a front edge side is fixed to a front edge side of a sitting portion frame 14, is resiliently connected to a back edge side of the sitting portion frame 14 via a movable frame 34 and a torsion bar 46, which is a resilient member. The cushion material 20 has a spring zero characteristic in which a spring constant of a portion that supports a protrusion portion of the sitting person is smaller than a spring constant of other portions. This vehicle seat 10 makes smaller the energy of vibrations which are transmitted to a spinal column portion of the sitting person through the sitting portion frame 14, and peripheral portions thereof convert vibrations corresponding to fluctuations in the body and transmit these through the sitting portion frame 14. α waves of 10 Hz to 12 Hz, which occur in a relaxed waking state, are caused in the brain of the sitting person. Vibrations in a resonance frequency region are attenuated in amplitude and transmitted to the sitting person.
