Abstract: In a vehicle seat (10), a deformable portion (32) extends continuously from an edge portion of a placement hole (28) towards an outside of the placement hole (28). When the deformable portion (32) is plastically deformed by a fastening bolt (40), the deformable portion (32) does not readily deform so as to be pushed outwards, but deforms so as to be squashed. When a low press-contact force acts on a side face (32D), the deformable portion (32) does not readily perform plastic deformation, and an impact load imparted to a seatback frame (44) can be stably absorbed by the deformable portion (32). Impact load imparted to the seatback frame (44) can be continuously absorbed by the deformable portion (32) since the deformable portion (32) deforms continuously. Accordingly, impact load imparted to the seatback frame (44) can be efficiently absorbed by the deformable portion (32).

Abstract: A vehicle seat that may assure stiffness of a seatback and that may realize a reduction in weight. In the present rear seat for a vehicle, a substantially X-shaped X-rib (24) is joined to a panel frame (22) of a rear seatback. A first reinforcement portion (24A) of the X-rib (24) spans in a linear shape between an anchor wire (68), which is a point of action of a load, and a first supported portion (22A) of the panel frame (22), which is supported at a vehicle body via a turning hinge (48). A second reinforcement portion (24B), which has a length direction middle portion in common with the first reinforcement portion (24A), spans in a linear shape between a second supported portion (22B) of the panel frame (22), which is supported at the vehicle body via a turning hinge (56), and a third supported portion (22C) of the panel frame (22), which is supported at the vehicle body via a lock mechanism (64).

Abstract: TASK To improve the attenuation effect of a magnetic actuator against external disturbances. SOLUTION So that an attenuation effect owing to an electromotive force may be obtained in the magnetic actuator when a moveable part (coil support member and lens holder) supported by sheet springs is displaced, an electric resonance circuit is formed by connecting an accessory coil 26 in parallel to a drive coil 11 mounted on the moveable part, and the resonance frequency of the circuit electric resonance circuit is made to agree with that of a spring mass system of the magnetic actuator. As the drive frequency is typically in a range that substantially differs from the resonance frequency, a large damping force, effective against the resonant condition owing to external disturbances, can be obtained without substantially affecting the drive property.

Abstract: An actuator includes a blade spring of which one end is fixed to a fixed member and other end is fixed to a movable member. A driving unit moves the movable member. A position detector detects a distance to a flat portion of the blade spring, and a calculating unit calculates an amount of displacement of the movable member based on the distance detected by the position detector.

Abstract: In a vehicle seat, a central support member typically consisting of wire mesh or grid and supports most of the load of the vehicle occupant via spring members, and undergoes a relatively large displacement when the occupant is seated in the seat. Thus, by detecting the displacements of various parts of the central support member, preferably peripheral parts thereof, the magnitude of the total load and distribution of the load can be evaluated both reliably and accurately. Additionally, displacement sensors for measuring such large displacements are relatively inexpensive and easy to handle. Also, such sensors would not interfere with the existing seat designs, and would not be adversely affected by the equipment of the seat such as seat heaters.

Abstract: Battery packs with a plurality of rechargeable batteries connected in series so as to obtain a voltage required by a load device are detachably accommodated in a case. The battery packs are connected in parallel and each output thereof is modified to a predetermined voltage by a discharge control section. The battery packs are connected to a power source line of the load device. Each battery pack is connected through an information transmission line to a power source control section where charge and discharge thereof are controlled, as well as the lifetime is judged. Thus, only the lifetime-judged battery pack is replaced.

Abstract: A disk brake having members for keeping the friction pads in contact with the disk rotor in such a way that the wear of the friction members and the energy loss are kept to a minimum. The disk brake has a disk rotor, friction pads provided opposed to each other on both sides of the disk rotor, a caliper formed with a fluid pressure cylinder at least on one side of the disk rotor, and a piston slidably received in the cylinder for selectively applying braking force to the disk rotor by pushing the friction pads into sliding contact with the disk rotor. A resilient member is disposed between the piston and one of the friction pads provided opposite the piston for biasing the friction pads toward the disk rotor by a predetermined stroke, thereby keeping the friction pads in contact with the disk rotor at a predetermined surface pressure even while the brake is not applied.

Abstract: An open-topped disc brake comprises a disk and friction pads provided on opposite sides of the disk and having back plates. A caliper having a window and fluid pressure cylinders are provided together with pad pins extending across the window for supporting the friction pads. Pistons slidably received in the fluid pressure cylinders urge the friction pads against the disk. First and second shims are disposed between the friction pads. The first shims are provided near the friction pads with first claws provided on the first shims which resiliently embrace the back plates of the pads by straddling outer and inner edges of the back plates. Second shims are provided near the pistons with third claws provided on the second shims to detachably and resiliently engage the pistons. Second claws are provided on one of the first shims and the second shims for resiliently gripping the other of the first shims and the second shims so that the first and second shims are moved together.

Abstract: A disk brake having elements which enable the friction pads to retract together with the pistons when the braking fluid pressure is released, and which can also suppress brake squeaks. In order to retract the friction pads together with the pistons, first and second shims are disposed between the pad and the pistons on each side of the disk. The first shim, provided near the pad, has first claws gripping the back plate of the pad. The second shim, provided near the pistons, has third claws resiliently engaging the pistons. The first or second shims have second claws resiliently gripping the other shims so that the first and second shims can slide relative to each other in the radial direction of the disk.

Abstract: An improved disk brake which provides both low dragging torque and good pedal feeling even on ABS-equipped vehicles with which the working fluid pressure is around or over 140 kgf/cm.sup.2. The disk brake has a piston seal fitted in a groove formed in the cylinder. The piston seal is deformed when the brake piston is advanced by fluid pressure to press the pad and retracts the piston by its spring-back force when the fluid pressure is released. The width W of chamfer provided at edge of the seal groove is set to 1.0 mm or over and the hardness of the piston seal is set to 75.degree. IRHD or over.

Abstract: A disk brake assembly has a piston retraction structure which can keep the space between the pad and the disk constant while the brake is not being applied by varying the distance the piston is retracted with the fluid pressure applied to the disk brake. The piston retraction structure has a piston seal fitted in a seal groove formed in the inner surface of a cylinder of a caliper. When a piston is advanced under fluid pressure, the piston seal is pulled by the piston and deformed until it fills up the gap defined by a chamfer formed along the edge of the seal groove. When the fluid pressure is removed thereafter, the piston is retracted by the resilient restoring force of the deformed piston seal. The piston seal is made of a rubber having a hardness of 80 IRH or more. In another arrangement, the piston seal has its outer-diameter portion fitted in the seal groove with a zero gap or with an interference.
