Abstract: A secondary battery includes an outer package member and a battery device. The outer package member has flexibility. The battery device has an elongated shape and is contained inside the outer package member. The battery device includes a positive electrode and a negative electrode that are stacked on each other in a thickness direction of the battery device, with a separator interposed between the positive electrode and the negative electrode. The positive electrode and the negative electrode are each a sheet having a substantially rectangular shape. The battery device includes compression-bonding regions and a non-compression-bonding region other than the compression-bonding regions. The positive electrode, the negative electrode, and the separator are compression-bonded to each other in the compression-bonding regions that are provided at least at two respective positions opposed to each other in a peripheral edge part of the substantially rectangular shape.

Abstract: In a seat back of automotive seat with an inflatable cushion device, an inflatable cushion element and a pair of air supply units are provided as constituent elements of the inflatable cushion device. In particular, a pair of support wire elements are provided to a seat back frame in the seat back so as to supportively receive the two air supply units, respectively. Specifically, those two support wire elements are fixedly connected with respective two upper portions respectively of two lateral frame portions of the seat back frame.
