  • Patent number: 6325746
    Abstract: The present invention relates to a cushioning mechanism for an exercise apparatus disposed between a turning shaft under the main body of the exercise apparatus and a supporting element. The clamping cushioning mechanism includes two clamping bodies corresponding in form each of which contains a clamping element between which a receiving part is formed for fastening a cushioning soft pad. Thereafter, a rolling shaft is disposed at the relatively external side of each of the two clamping bodies so that, when a frame is loaded and pressed down, the stress will be transmitted from the turning shaft to two clamping bodies while the clamping bodies sink because pivoting holes at the relative center are loaded, however, the rolling shaft at two side thereof create an upward reactive force by means of their contact with the supporting element so that the clamping elements of the clamping bodies are enable to be clamped inwardly in order to achieve an expected cushioning effect.

  • Patent number: 6325412
    Abstract: A fasten-on air bag device comprises an air bag housing which is attachable to the seat restraints and can be fastened-on by occupant; a crash sensing system for sensing and evaluating the crash data; an inflator installed inside the air bag housing, a plug-in signal-transmission receptacle and a detachable plug affixed to the air bag housing. By coupling with the plug-in signal transmission receptacle, the fasten-on air bag device can be utilized not only on the front seats but also the rear seats, and can be applied on all kinds of vehicles such as cars, buses, trains and airplanes. The direction of explosion is guided by the guiding core to assure the deployment of the air bag go outward and forward away from the occupant's body instead of aiming toward the occupant's body. In addition, the protective shield lining and the spread plastic lobes further protect the occupant's body. Therefore, the explosive expansion of the air bag would less likely cause harm to the occupant.

  • Patent number: 6321398
    Abstract: A multipurpose body-turn-over apparatus mainly including an elevator, a driving mechanism, ropes, a net, suspension fittings, a vibrator, and a controller. The controller sets operating time and speed, and time pause at reverse of the apparatus, and the elevator is adjustable in height. The driving mechanism drives a displacement shaft of the driven assembly to move or rotate, so that ropes hanging from two ends of the driven assembly to connect the net are alternately pulled up and lowered, helping a patient lying on the net to regularly turn over or lie on side to avoid bedsore, or do rehabilitation exercises. The vibrator may alternately pull and lower ropes connected to two sides of the net at high frequency. The apparatus may be designed into heavy-duty or light models to meet different requirements and can be freely moved for use with different sickbeds.
