Abstract: Provided is an electrical connection unit disposed in an automobile and performing relay in supplying electrical power from a first power source to a load apparatus. An electrical connection unit includes: a first electrical power path and a second electrical power path connected to a load apparatus; a third electrical power path connected to a first power source; a power source connection part which can be connected to a second power source; a first fuse attachment part which can attach a first fuse connecting the first electrical power path and the third electrical power path and is connected to the first electrical power path and the third electrical power path; and a second fuse attachment part which can attach a second fuse connecting the second electrical power path and the third electrical power path and is connected to the second electrical power path and the third electrical power path.

Abstract: There is provided a cushion spring including: a formed wire bridged to a seat cushion frame in a seat front-rear direction; and a resin member joined to the formed wire. A center wire and a side wire of the formed wire each include a plurality of crank-shaped portions that are bent to fold in a crank shape to one side and the other side in a seat width direction alternately. The resin member includes a deflection restricting portion that connects the plurality of crank-shaped portions to restrict a divergence in the seat front-rear direction between three or more crank-shaped portions, the three or more crank-shaped portions being formed in the side wire and arranged side by side consecutively in the seat front-rear direction.

Abstract: There is provided a cushion spring including: a pair of formed wires bridged to a seat cushion frame in a seat front-rear direction and are arranged side by side in a seat width direction; and a resin member joined to the pair of formed wires. The resin member includes a rear connecting portion and a pair of deflection restricting portions, the rear connecting portion extending to connect between a side wire and a center wire and between the center wires in the seat width direction in a region on a seat rear side of an ischium supporting portion of the pair of formed wires that supports an ischium of the seated occupant via a seat cushion pad, the pair of deflection restricting portions extending from the rear connecting portion to connect all crank-shaped portions in the seat front-rear direction.

Abstract: A movable headrest includes a base member including a headrest stay; a movable member that is slidable relative to the headrest stay; and a lock mechanism that locks the movable member such that the movable member is restrained from sliding relative to the headrest stay. The movable member includes a flexure part that bends due to a load received from a head of an occupant, a frame part that supports the flexure part, and an engaging portion. The frame part includes a sliding portion that slides relative to the headrest stay, and when the flexure part is bent such that the engaging portion is moved relative to the frame part, the movable member is unlocked.

Abstract: To provide a power generation member having a high power generating capacity, a power generation device using the same, and a power generation system. A power generation member 1 includes: a piezoelectric element 2 in which electrodes 2a and 2c are formed on both main faces of a plate-shaped piezoelectric ceramic 2b; a pressing member to press one main face of the piezoelectric element 2; and a support member 4 to support the other main face of the piezoelectric element 2, wherein the support member 4 supports an outer rim of the piezoelectric element 2, and the pressing member 3 presses the piezoelectric element 2 at a part inside the support member 4 with a planar pressing face. It is possible to reduce cancellation of the generated charge, as well as to allow the piezoelectric ceramic 2b to deform sufficiently to produce large strain by pressure energy generated by a walking man or vibration energy generated by a running car and the like. As a result, it is possible to effectively obtain large electricity.
