A D-type screwing assembly for furniture contains a retaining member including a hole defined in the retaining member, with a plurality of ribs defined on two sides of the retaining member, and with a slot formed on a top end of the retaining member. A screw member includes at least two orifices defined on a head end of the screw member and a thread section formed on the screw member to screw with the hole of the retaining member. A rotary member includes at least two posts extending outwardly from a front end of the rotary member, with a number of the at least two posts corresponding to that of the at least two orifices of the screw member, so that the at least two posts of the rotary member are fitted into the at least two orifices of the screw member correspondingly.

A seat assembly is provided for supporting in an automotive vehicle. The seat assembly comprises a seat cushion and a seat back pivotally coupled to the seat cushion for movement between a reclined seating position and a fold flat position. A recliner assembly is coupled between the seat back and the seat cushion to provide pivotal movement of the seat back. A riser assembly is pivotally coupled to the seat cushion and pivotally latched to the floor to allow pivotal movement of the seat cushion between a horizontal seating position and a forwardly upright tumbled position. A release mechanism is coupled between the seat back and the riser assembly for automatically synchronizing actuation of the recliner assembly and the riser assembly to provide movement of the seat assembly to the tumbled position in response to the pivotal movement of the seat back to the fold flat position.

A fastening device includes a fixing bracket and a fastener. The fixing bracket includes a fixed arm and two adjusting arms respectively connecting at two ends of the fixed arm. Each of the two ends of the fixed arm defines a plurality of spaced retaining slots. The retaining slots are located at different positions along the fixed arm. Each of the two adjusting arms has a sliding end retained selectively in one of the retaining slots and an opposite fixing end. The fastener extends through the fixing end of each of the two adjusting arms.

A heat dissipation assembly comprises a heat sink for being disposed on an electronic component mounted on a printed circuit board, and a pair of fasteners for securing the heat sink on the printed circuit board. Each fastener comprises a sleeve extending through the printed circuit board, a latch received in the sleeve, a stretchable pole inserted through the sleeve and a handle pivotably fixed to the pole. The pole is raised by rotation of the handle to a locked position. At the locked position, the handle downwardly acts on the heat sink, and the pole pushes the latch out of the sleeve. The latch presses against the printed circuit board upwardly to realize an intimate contact between the heat sink and the electronic component.

A fastener includes a fastener post, a sleeve, a nut and an elastic element. The fastener post includes a shaft, a tapered portion and a threaded portion. The sleeve includes a smooth portion and a clamp portion having a number of resilient strips. The nut is threaded onto the threaded portion. The elastic element is disposed around the sleeve and compressed between the nut and an ear of a heat sink to generate a resilient force. The resilient force moves the tapered portion of the fastener post into the sleeve such that the strips of the clamp portion of the sleeve are tilted outwardly to tightly abut against a bottom of a printed circuit board on which the heat sink is mounted.
