Abstract: An aircraft seat which can receive the load of a sitting person with only a back plate member, using no seat back frame, thus eliminating the need for sacrificing the sitting space, which results from the existence of the seat back frame, and at the same time, allowing the weight of the seat to be reduced, is provided. The aircraft seat (1) on which an aircraft passenger is to sit comprises a seat back (10) made up of a back plate member (11) that a cushion (12) is installed onto a front face (11a) thereof for receiving the back of a sitting person, and a reinforcing member (13) which is disposed on the rear face (11b) of the back plate member (11) for reinforcing the back plate member (11), and said back plate member (11) is formed in the shape of a curved surface which enhances the surface rigidity.

Abstract: A platform monitoring system includes a camera for capturing a situation on a platform. An image captured by the camera is transmitted from a light emitter on the ground side as an optical signal and also transmitted from a transmission antenna on the ground side as a radio wave signal. These signals are received by an optical receiver and a reception antenna, respectively, mounted in a leading end portion of a vehicle. When the vehicle is positioned in a region around a stopping position, an image carried by the optical signal is selectively displayed on a monitor disposed near an operator's seat in the vehicle. When the vehicle is positioned out of the region around the stopping position, an image carried by the radio wave signal is selectively displayed on the monitor near the operator's seat in the vehicle.

Abstract: An astral lamp includes a light source and a concave mirror. The concave mirror reflects light emitted by the light source and condenses the reflected light on a light source side toward an illumination area remote from the light source. The concave mirror is constituted by a plurality of concave mirror surfaces that form one parabolic mirror of revolution as a whole. The mirror surfaces respectively have curved surfaces for separately reflecting the light emitted by the light source and condensing the reflected light toward an entire portion of the illumination area.

Abstract: An aircraft seat apparatus installed in a cabin of an aircraft includes a seat portion, a slide mechanism, bulkheads, and a seat portion driving unit. The seat portion is movable in a back-and-forth direction. The slide mechanism supports the seat portion to be movable in the back-and-forth direction. The bulkheads support the slide mechanism to form a space under the seat portion together with the seat portion, and are fixed to a cabin floor member. The seat portion driving unit is arranged under the seat portion to move it in the back-and-forth direction.

Abstract: An audible traffic signal adding apparatus for visually impaired persons includes two speakers and a control section. The two speakers are disposed at two ends of a crosswalk. The control section navigates a visually impaired person crossing the crosswalk by alternately outputting different sounds as in "back and forth call" operation from the two speakers disposed at the two ends of the crosswalk to the visually impaired person for a period during which crossing is permitted.

Abstract: The slide support base 62 protrudes from the supporting wall 56 of the support recess 52 in the casing main body 14 and the tube-shaped support part 122 on the side of the toilet lid 100 is supported by and capable of sliding over its cylindrical surface 65a. The rotational pin 70 of the viscous resistance mechanism 80 protrudes from slide support base 62 and the rotational pin 70 fits in the fitting recess 132 on the side of the toilet lid 100. That is, the toilet lid 100 is pivotably supported to the casing main body 14 by two support structures. To remove the toilet lid 100 from the casing main body 14, the toilet lid is raised to the upright position and then applied with upward force to be pulled out. Since the opening 124 and the opening 136 are formed in the tube-shaped support part 122 and the fitting recess 132, the toilet lid 100 is removed from the casing main body through them.

Abstract: Irrespective of limitation of a back-rest operating speed of a in a normal angle range, a raising speed of the back-rest in the case where the back-rest is greatly raised forward beyond the angle adjusting range is made faster. A back-rest angle adjusting apparatus 1 for a seat of a cylinder type in which an enlarged diameter portion 37 is constituted in an inner wall portion of a cylinder 2 opposed to a piston 16 in the vicinity of said back-rest angle adjusting apparatus 1, a bypass passage 38 is formed between the inner wall of the cylinder 2 and the outer periphery of the piston 16 when the enlarged diameter portion 37 on the cylinder 2 side is opposed to the piston 16, and a rod side chamber R and a head side chamber H within the cylinder 2 defined by the piston 16 are caused to communicate with each other by said bypass passage 38.

Abstract: A headrest for seats which is recessed in a central recess of the seat and is capable of tilting forward so as to be used as a headrest, and automatically returning this headrest to its original position by tilting it forward more than a predetermined angle with respect to the seat back. The headrest is formed on an upper portion of a seat back and is swingably supported by means of a hinge mechanism equipped with a ratchet mechanism. The hinge mechanism 8 includes a movable hinge portion fixed on a lower portion of a supporting frame of the headrest, and a hinge main body fixed on a seat back frame so as to be hingedly supported on a rotational shaft together with the movable hinge portion. Further, there is provided a return spring together with the supporting frame of the headrest that returns the headrest to its recessed position.

Abstract: A leg structure wherein a seat bottom (4) and a seat back (5) are mounted on a base frame (3) mounted bridgewise between front and rear beams (1) and (2) to constitute a seat. A diagonal member (8) is extended bridgewise from the front beam (1) supported by a front leg (6) to a lower rearward portion of the seat, a rear leg (9) for supporting the rear beam (2) is supported and fixedly mounted on a substantially intermediate part of the diagonal member (8), and lower end portions of the front leg (6) and the diagonal member (8) are fixed to a floor side rail through fixing fitting members.

Abstract: An armrest (1) comprising an armrest body provided with a cavity (2) under a cocktail tray to house a television set (4), and a hinge mechanism (6) provided with a turning unit (10) and attached to the upper front end of the armrest body so that the turning unit (10) can be turned into and out of the cavity (2). A television set is mounted on the extremity of the turning unit (10). The television set (4) is held in an operating position by the turning unit (10). When not used, the television set (4) is housed in the cavity (2). The armrest (1) capable of housing the television set (4) is applied to seats to be installed on aircraft, railway rolling stocks and vehicles including buses.

Abstract: A supporting structure for supporting a TV set on an armrest of a seat of an aircraft or other vehicle so that the TV set can be turned in a vertical plane between an operating position outside a cavity formed in the front portion of the armrest and a housing position within the cavity, can be turned about a vertical axis at the operating position, and can be tilted with respect to the vertical axis. The supporting structure includes a hinge mechanism provided at the front upper end of the cavity, and a turning mechanism supported on the hinge mechanism and supporting the TV set so that the TV set can be turned at the operating position in both horizontal and vertical planes.

Abstract: A front leg (1) is formed by an upright support rod extending vertically above a fixing stud (8), a rear leg (2) is formed by both a lower support rod (2a) extending on a diagonal line joining the upper end of the front leg and the lower end of the rear leg and an upper support rod (2b) contiguous to the lower support rod (2a) in an upper position relative to the lower support rod, the upper support rod (2b) being curved arcuately and inclined rearwardly upwards, and an energy absorber (12) is mounted bridgewise as a diagonal member between the upper end portion of the front leg and the lower end portion of the rear leg, to constitute a leg structure. Accordingly to this leg structure, a striking energy is absorbed by an anti-plastic deformation force induced when the rear leg (2) and the energy absorber (12) is deformed plastically under an impact larger than a predetermined value, and the seat is held at its supported posture in normal use.
