摘要： A seat reclining device has a first arm member adapted to be secured to the seat cushion frame or the seat back frame, a second arm member rotatably supported by the first arm member and adapted to be secured to the other of the seat cushion frame and the seat back frame, and a plurality of pawls for locking an adjusted angle of the seat back. The pawls are disposed on the first arm member and include at least a first pawl and a second pawl. Only one of the first and second pawls is provided with an engaging portion. The second arm member is provided with a receiving portion for preventing the engagement of the outer gear with the inner gear when the engaging portion contacts the receiving portion during relative rotational movement of the first and second arm members.

摘要： A seat slide mechanism for vehicles includes a screw member extending longitudinally within an interior portion of the upper rail and a nut member engaging with the screw member. The nut member extends downwardly between the opposed walls of the upper rail to the base of the lower rail to form separated spaces at the both sides of the nut member and between laterally elongated slide members of the upper rail and the base portion of the lower rail. These separated spaces are helpful in arranging the rollers without any interference with the nut member or the screw member.

摘要： A power seat frame assembly includes a screw nut and rod assembly which is pre-assembled as a unit before being mounted on a bracket fixed to a rail for vehicle's seat. A gear box of the screw rod and nut assembly is disposed merely in a space between opposed walls on the bracket and the screw rod is received in an opening upper recess of the bracket. Thus, the arrangement of the screw rod and nut assembly on the bracket becomes easier.

摘要： A keyboard apparatus includes a key matrix having key switches disposed at intersections between rows and columns forming a matrix and a control unit for selecting a row and a column of the key matrix to sense a state of a key switch disposed at an intersection of the selected row and the selected column of the key matrix. The apparatus includes a first confirmation unit for sensing, in a first period of time, a key switch state of the key matrix to confirm whether or not two or more depressed keys exist on a row of the key matrix and a second confirmation unit for sensing again, in a second period of time, a key switch state of the key matrix such that when two or more depressed keys exist on a column of the key matrix, a confirmation is made to determine whether or not two or more depressed keys exist on the row on which the key depression is found in the key matrix. The apparatus temporarily reserves, when the first and second confirmation units confirm that two or more depressed keys exist both of the column and the row of the key matrix, a depression processing of a key switch associated with the depressed keys.

摘要： A mobile communication system including a plurality of radiotelephone base stations respectively covering a plurality of cells to define in combination a service area, a mobile unit capable of communicating with the radiotelephone base stations, and a radiotelephone control unit for connecting together each of the base stations and an ordinary telephone network, setting up and releasing a speech path between the each radiotelephone base station and the mobile unit, and adding a speech path for communication with another radiotelephone base station which is able to communicate with the mobile unit as it moves. The mobile unit is adapted to transmit and receive a plurality of channels at the same time so that it is capable of communicating with a plurality of radiotelephone base stations and registering its position to these base stations. The mobile unit successively registers its position to radiotelephone base stations with which it can communicate as it moves, so that the mobile unit can communicate with a telephone set in the telephone network without instantaneous disconnection via all the base stations where it has registered the position.

摘要： A seat adjustment device adjusts the pivoting angle formed by a first seat member and a second seat member. A hinge shaft connects at a first connection point, the first seat member, and the second seat member. An arm section and a connection mechanism are connected at a second connection point. The positions of the axes of the first connection point, the second connection point, and a pivoting section are set in such a manner that, when a load is applied to the front end of either the first seat member or the second seat member, the distance from the second connection point to the axis of the pivoting section is less than the distance from the first connection point to the second connection point with respect to the direction perpendicular to the line of action of a load applied to the second connection point.

摘要： A vehicle seat device includes a seat cushion frame and a seatback frame including a lower-side frame supported at a lower end portion thereof to be tiltable relative to a rear end portion of the seat cushion frame, an upper-side frame arranged at an upper portion of the lower-side frame, and a center bending mechanism coupling the lower-side frame and the upper-side frame to be bendable forward, wherein the center bending mechanism bends the upper-side frame about a rotational center that is ahead of a seatback outer layer covering a front surface of the seatback frame. The movement of the upper-side frame when tilted comes close to the movement of the passenger who bends forward. The slip between the seatback outer layer and the back of the passenger can be minimized, and thus, it becomes possible to lessen an uncomfortable feeling of a passenger.
