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 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： A seat provides a band-like support for the body sides of a user so as to reduce the supporting pressure on the user's lumbar and to hold the user's upper body stably. In this seat, the center of a load to be received in regions symmetrically divided to a vertical central line of the seat are positioned outside of a back region defined by left and right angulus inferior scapulae and by the upper ends of iliac bones. Moreover, the load ratios in the individual regions are not more than 25% in the region corresponding to a region extended downward from the back region.

摘要： In a vibration control apparatus, a physical value influencing characteristics of a suspension for supporting a vibrating body and a state value representing movement of the suspension are detected. A frequency distribution of these values with respect to levels is calculated every predetermined period of time. A target control force is calculated on the basis of the frequency distribution in consideration of a continuous change in external state. An actual control force (detection control force) is calculated by the detected physical value. The suspension characteristics are continuously, variably controlled so as to equivalently generate a control force corresponding to a difference between the target and detection control forces. As a result, the target control force is equivalently applied to the suspension, thereby damping the vibrations. The vibration control apparatus can generate an optimal target control force free from the influence of an external state change on the basis of the frequency distribution of the state and physical values of the suspension.

摘要： An apparatus for controlling steering of wheels of a vehicle comprises a control means, a driving means, and an actuator means. The control means comprises a feed forward signal operating means, a feed back signal operating means for generating signals for variables representing vehicle behaviors and output from a vehicle behavior sensor, and a control signal operating means for calculating a difference or sum of the signals output from the feed forwad and feedback signal operating means. The feed forward signal operating means comprises a steering angle signal circuit, a steering angular velocity signal operating circuit, a steering angle signal operating circuit having a first coefficient circuit for multiplying a steering angle signal with a coefficient, and an adder for adding the outputs from the steering angle signal circuit, the steering angle signal operating circuit, and the steering angular velocity operating circuit. A behavior correction capacity against a side wind or disturbance is very high, and a steering system can be controlled to shorten the response time for changes in vehicle behaviors with respect to a steering input, thereby providing optimal steering. The control means further comprises a gain changing means to supply optimal coefficients to the feed forward and feedback signal operating means.

摘要： A vibration control apparatus detects a physical value influencing characteristics of a suspension supporting a vibrating body and a state value representing movement of the suspension, calculates an optimal target control force in consideration of an external force or disturbance acting on the suspension on the basis of the physical and state values as outputs from a state detecting system, calculates the detection control force corresponding to the detected physical value, and continuously variably controls the suspension characteristics so as to generate a control force corresponding to the difference between the target and detection control forces in consideration of the external force or disturbance acting on the suspension, whereby vibrations are prevented by equivalently applying the target control force on the suspension.

These actuator assemblies have pressure chambers, and each is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding wheel as respective results of supplying or discharging of working fluid to or from its pressure chamber.

Wheel loading detection means are provided for sensing parameters representative of the loadings imposed by the vehicle body on the wheels, and vehicle height detection means are provided for sensing the heights of the vehicle above the wheels. A means for computing and control controls the working fluid supply/discharge means, based on the deviations of the actual wheel heights from standard wheel heights, and carries out control adjustment of the actual wheel heights to the standard wheel heights by, at least when the vehicle speed is below a determinate value, carrying out a correction to the adjustment control of the working fluid supply/discharge means, based upon the deviations of the actual wheel loadings from standard wheel loadings, by an amount appropriate substantially to eliminate the loading deviations.
