Abstract: A raincoat-integrated backpack assembly includes a raincoat, and a bag body that confines a main receiving space therein and that has a raincoat retaining pouch which confines a raincoat receiving space therein for receiving the raincoat, a pouch opening for permitting access to the raincoat receiving space, and a closure device for closing the pouch opening. A connecting member is disposed in the raincoat receiving space, and includes male and female interlocking members which are respectively secured to the raincoat and the bag body and which are engageable to each other so as to permit attachment of the raincoat to the bag body.

Abstract: A limb guard serves to protect a part of a limb from an external impact force and includes an elongate pad member, an elongate sheet layer mounted on the pad member to form an accommodation space between the elongate sheet layer and the elongate pad member, and a one-piece resilient impact absorbing member. The shock absorbing member is inserted in the accommodation space, and has a longitudinally extending central section of a first thickness adapted to resist and consequently absorb the external impact force applied thereon, and two lateral wing sections which are integrally formed with and which extend laterally from two longitudinal edges of the central section.

Abstract: A limb guard for protecting a part of a limb from an external impact force includes an elongate pad member to shield the part of the limb, and a one-piece resilient impact absorbing member. The pad member extends in a lengthwise direction of the limb and has a rear surface to face the limb, and a front surface. The impact absorbing member is disposed upon the pad member, and includes two lateral end portions and a plurality of cushioning units in the form of consecutive box pleats between the lateral end portions.

Abstract: A cushion device is adapted to be disposed in a carrying bag and includes two curved plates with different radii of curvature. The curved plates are connected to each other and form a void therebetween.

Abstract: A buffer structure improvement of a body part protector having a pad, and a board having a generally arcuate cross-section with a string. Between the pad and the board is a buffer web attached to the board with a buffer spacing between the web and the board.
