20080272639 | Gear-Driven Adjusting Assembly for Continuous Adjustment of Seat Angle - A gear-driven adjusting assembly for continuous adjustment of seat angle is disclosed. A external gear plate of the gear transmission mechanism is mounted in a internal gear plate with a eccentricity therebetween. An external cam of a gap removing mechanism is mounted between a central boss of the internal gear plate and the inner hole of the external gear plate. An internal cam is mounted between the inner hole of the external cam and the central boss of the internal gear plate, and a spring is mounted between the two cams, which form an eccentric cam mechanism. A central shaft of a driving mechanism is provided in the hole of the central boss of the internal gear plate, a driving block of the driving mechanism is provided between the internal cam and external cam. When the spring is in a free state, the internal cam and the external cam are wedged tightly to remove the seat gap; the driving block of the driving mechanism can overcome the elastic force by a moment to release the wedge effect of the gap removing mechanism, such that the gear transmission mechanism is driven for transmission and rotation, so as to achieve the purpose of adjusting seat angle. The assembly according to the present invention has the features of compact configuration, small gap, high strength as well as high universalness, and can conveniently implement the function of manual adjustment, electrical adjustment and continuous adjustment of the seat back angle. | 11-06-2008 |
20080197687 | RECLINER REGULATING DEVICE - The present invention discloses a recliner regulating device comprising a cam, a return spring, a housing plate, a ratchet gear connected with a central shaft. The external hook of the return spring is fixed in a hole of the housing plate. Sliders are fitted in sliding grooves of the housing plate with the bosses of the sliders being attached with the sliding grooves of the cam. Wedges are fitted in the sliding grooves of the housing plate with the bosses of the wedges being attached with the sliding grooves of the housing plate. The sliding grooves for sliders are perpendicular to the sliding grooves for wedges. A two-point locking-up is formed between the self-locking surfaces of the sliders and the self-locking surfaces of the wedges after the position of the cam is fixed through the central shaft under the action of the return spring. | 08-21-2008 |
20080196542 | Recliner regulating device - Described herein is a recliner regulating device comprising a locking cam, an unlocking cam with a thickness less than the locking cam, a ratchet gear, a coulisse and a return spring connected with a central shaft. The locking cam is connected with the unlocking cam. Sliders are connected with the unlocking cam and sliding grooves. A jacket is connected with the ratchet gear and the coulisse. The return spring is connected with the coulisse. The thickness of the locking cam and the unlocking cam may be respectively designed in terms of the stress applied thereon. Since the locking cam and the unlocking cam are separately produced, structure of the die is simplified and service life of the die is improved significantly. The locking cam and the unlocking cam may be manufactured by punch, which leads to a greater production efficiency. | 08-21-2008 |
