The present invention prevents a three-dimensional fabric arranged in front surfaces of speakers from flapping due to sound. In the respective front surface sides of speakers 20, 30, sound-emitting direction regulating members 23, 33 that include annular portions 231, 331 that project forward by a predetermined distance are arranged. A three-dimensional fabric 421 is tensioned and arranged so as to cover the front surface sides of the sound-emitting direction regulating members 23, 33. When the three-dimensional fabric 421 is pressed against the annular portions 231, 331 configuring the sound-emitting direction regulating members 23, 33, the annular portions 231, 331 bite into the three-dimensional fabric 421 since the three-dimensional fabric 421 has a predetermined thickness. The annular portions 231, 331 are provided so as to surround diaphragms 221, 321 of the speakers 20, 30. Sound output from the speakers 20, 30 passes inside the annular portions 231, 331. However, the periphery of a region of the three-dimensional fabric 421 in which sound passes is supported by the biting of the annular portions 231, 331, thereby preventing the three-dimensional fabric 421 from flapping widely in response to the sound.

A vehicle seat suitable for weight reduction is provided. A left and right side frames 11 constituting a cushion frame unit 10 are constituted of plate-shaped frames 111, 112 which are long in a forward and backward direction and formed of a thin material made of metal with a predetermined thickness or less, a plurality of beams 121 to 125 are bridged across the side frames 11, and moreover, one or both of the side frames 11 is or are supported on a seat slide device 40 via a truss support part. In other words, the side frames 11 disposed in a direction substantially orthogonal to the plurality of beams 121 to 125 serve the role of stringers, and as a result, rigidity in the forward and backward direction of the side frames 11 in particular is high rigidity of a predetermined value or more even if they are made of a thin material, and they can be reduced in weight.

A seat slide device suitable for weight reduction is provided. The seat slide device (40) is structured such that lower rails (41) and upper rails (42) are both formed to be substantially symmetrical bilaterally across a center in a width direction, and lock mechanisms (43) are provided on both sides of the upper rails (42), and each of them can be engaged with the lower rails (41) to lock them. An entire structure combining the lower rails (41), the upper rails (42) and the lock mechanisms (43) is substantially symmetrical forward and backward as well as bilaterally, and a force applied to the lower rails (41) and the upper rails (42) can be absorbed substantially evenly forward and backward as well as left and right. Since the lock mechanisms (43) have an elastic lock member (430) in a substantially center part in a longitudinal direction, the lower rails (41) and the upper rails (42) are elastically deformable by which reduction of a biased load at a time of locking, improvement in vibration absorption characteristic, and the like are achieved, and a plate thickness of each material can be made thinner than conventional ones, thereby achieving weight reduction.

A biological body state estimation device which can capture not only activities of autonomous nerves but also an activated state of a brain function is provided. The biological body state estimation device is configured such that a homeostatic function level is sorted and acquired in a plurality of stages by using a biological signal obtained from the upper body of a person and each stage of the homeostatic function level is plotted in a time series in accordance with a time axis indicated on the lateral axis and displayed as a graph by display means. It is preferable that the highest part on the vertical axis of the graph is displayed as a highly active state and the lowest part as a function decline state. As a result, a state of fluctuation due to the 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 also captured.

A pillow exhibiting high ventilation and ensuring comfortable sleep. As a material (3) filling a cover member (2) exhibiting ventilation, at least one cushion material (10) produced by laminating a plurality of sheets of three-dimensional knitted goods (11, 12) is employed. Since a lamination of a plurality of sheets of three-dimensional knitted goods (11, 12) is employed as the cushion material (10), air can move easily in the vertical direction, as well as in the right/left direction and the front/back direction with the head as the center, and high ventilation can be ensured. When an air cushion (20) for sucking/discharging air according to variations in load is employed by being laid on top of the cushion material (10) provided with the three-dimensional knitted goods (11, 12), air is sucked/discharged automatically as the head moves to promote air flow passing between yarns of the three-dimensional knitted goods thus enhancing ventilating function furthermore.

A state change of a person is captured with timing closer to consciousness of the person. A frequency slope waveform of a time series signal of a pulse wave of a body of a person detected by an air pack is obtained by a frequency slope time-series analyzing and computing means 612 and a frequency fluctuation time-series waveform is obtained by a frequency fluctuation time-series analyzing and computing means 613. By comparing changes of two waveforms with each other in a waveform determining means 614, a state change of a person can be captured with timing closer to consciousness of the person. A sleep-onset point can be specified clearly based upon the case where a fluctuation waveform steep gradient portion indicating a steep gradient change emerges in the frequency fluctuation waveform, and amplitude and a base line position of the frequency fluctuation waveform or the frequency slope waveform are in predetermined ranges. Further, when a mean slope line of the fluctuation waveform steep gradient portion is approximately parallel to a mean slope line of the slope waveform steep gradient portion in the frequency slope waveform before emergence of the fluctuation waveform steep gradient portion, a sleepiness waveform is determined, so that a sleepiness state leading to sleep onset can be detected.
摘要:
There is provided a power seat slide device capable of changing not only to an electric operation but also to an manual operation, and preventing half-lock in spite of a manually operable structure. For front-rear movement, a rack (21) attached to a lower rail (11) and a pinion (22) meshed with the rack (21) are used, and a driving force of a motor (51) is transmitted to the pinion (22), which enables the use in an electric mode. On the other hand, because no slide screw is used, while the motor (51) is not energized, rotating the pinion (51) causes an output shaft of the motor (51) to rotate, so that manual adjustment becomes possible.
