摘要： A biological body state estimation device configured such that a homeostatic function level is sorted and acquired in plural stages by using a biological signal obtained from an upper body of a person and each stage of the homeostatic function level is plotted in time series in accordance with a time axis indicated on the lateral axis and displayed as a graph by a display. A highest part on the vertical axis of the graph can be displayed as a highly active state and a lowest part as a function decline state. Therefore, a state of fluctuation due to autonomous nerves as an attempt to maintain homeostasis, progress of a feeling of fatigue, and a state stimulated by activation of the brain can be captured as a periodic function. Moreover, a sleep prediction phenomenon can be captured.

摘要： Seat structure designed to reduce weight and improve various functions such as impact absorbency, vibration absorbency. A torsion bar arranged along a width direction, and an arm connected to the torsion bar and enforced in a direction of falling backwards in a normal state are provided in the rear of a seat cushion, and a cushioning member is arranged between a supporting frame supported by the arm and a front frame provided at the front of the seat cushion, whose front edge is vertically movable rotationally. When working a pedal or standing up, since the front edge of the front frame is forced to move in a downward direction by a leg portion, a haunch supporting portion of the cushioning member is relatively lifted upward, so that support force to lift up the haunches works.

摘要： The object of the present invention is to suppress rebound of a human body by making a reaction force small due to a large damping ratio. A bulging portion 11 is formed at a seat cushioning member 14 which is a tension structure. This structure has a structure of changing the damping characteristics functioned by the change in strain energy and tension by deformation created by a plane wave of the tension structure in accordance with the magnitude of the excitation force of an inputted vibration. Therefore, since the damping characteristics function with a small damping ratio to an input of a small excitation force, it can relieve the vibration with a phase difference due to the spring property of the seat cushioning member 14 and/or a back cushioning member 24, and to an input of a large excitation force, by increase of the strain energy and decrease of the tension, the damping characteristics function with a large damping ratio and a long operating time, so that rebound of a human body upward can be suppressed.

摘要： A technology to grasp a state of a human being more accurately is provided. The technology is provided with means for acquiring a time-series waveform of a frequency from a time-series waveform of a biological signal sampled from the upper body of a human being and for further acquiring a time-series waveform of frequency slope and a time-series waveform of frequency fluctuation and for applying frequency analysis to them. In the frequency analysis, a power spectrum of each frequency corresponding to a functional adjustment signal, a fatigue reception signal, and an activity adjustment signal, respectively, determined in advance is acquired. Then, a state of a human being is determined from a time-series change of each power spectrum. The fatigue reception signal indicates a degree of progress of fatigue in a usual active state and thus, by comparing it with degrees of predominance of the functional adjustment signal and the activity adjustment signal as their distribution rates, a state of a human being (relaxed state, fatigued state, state in which sympathetic nerve is predominant, a state in which parasympathetic nerve is predominant and the like) can be determined more accurately.

摘要： A human condition evaluation system, of which bio-signal analysis means includes a bio-signal peak value detection means for detecting a peak value for each cycle of an original waveform of a bio-signal data, and a power value calculation means for calculating a difference between the peak value at an upper limit side and the peak value at a lower limit side for every prescribed time range using respective peak values obtained by the bio-signal peak value detection means to thereby set the difference as a power value, is structured to determine a predictive signal for falling asleep from an active state into a sleep state. Different from conventional human condition evalution based simply on a Lyapunov exponent as an indicator, a new human condition evaluation system based on a functional status of an energy generation system of the living body is provided.

摘要： To provide A seat structure applicable to both a normal posture and a resting posture and providing a sufficiently relaxed resting posture and an excellent comfort.According to the present invention, a seat reference point adjustor for shifting a seat reference point in the resting posture anterior to a seat reference point in the normal posture is provided. With this structure, the resting posture can be taken without tilting its seat back itself backwardly. Since the seat back is not tilted backwardly, a leg room (footrest) space of a rear seat is not limited.
