Abstract: A ski or ski-like device with an improved edging feature to assist skiers in edging during icy conditions. The edging feature includes a structure and method that provides a lateral edge on the inside of the ski that can extend into the snow surface beneath the bottom surface of the ski. When the ski is turned (i.e., rotated about its longitudinal axis) the extended inside edge of the downhill ski digs into the snow surface to provide improved gripping and control. The edge adapted to extend beneath the bottom surface of the ski is provided either by attaching an edge that extends below the bottom surface of the ski, or by providing a bottom surface of the ski in the region adjacent to the extended edge that is arranged to yield under pressure, to expose the extended edge when vertical force is applied to the bottom surface of the ski during a turn.

Abstract: A vehicle occupant restraint device having a gas bag module includes a gas generator for inflating a gas bag, at least one discharge opening that is formed in a rigid component of the gas bag module, through which gas that is produced by the gas generator and conveyed into the gas bag can be discharged, and at least one closing device for the discharge opening. The closing device has an adjusting device and a plurality of covers of different pressure sensitivities. A specific one of said covers is placed in front of the discharge opening by the adjusting device even before the gas bag module is activated, so as to close the discharge opening until a pre-established gas bag interior pressure is reached that is associated with the specific cover, and, when this interior pressure is exceeded, to at least partially release the discharge opening through bursting.

Abstract: An air bag formed from two layers of fabric using a one-piece weaving technique has a peripheral seam at the edge of a region adapted to be inflated. Beyond the seam there are a plurality of chambers and gas escaping from the inflated region through the seam must inflate these chambers thus creating a back pressure to reduce the flow of escaping gas.

Abstract: A vehicle body includes a front frame, a rear frame, a control unit, a fixing screw, a battery, and a locking unit. Thus, the rear frame is combined with and detached from the front frame easily and rapidly, thereby facilitating a user assembling and disassembling the vehicle body. In addition, the fixing hooks of the front frame are snapped onto the fixing stubs of the rear frame, and the locking hook of the control unit on the support post of the rear frame is locked in the locking hole of the front frame, thereby forming a three-point support structure by the fixing hooks, the fixing stubs and the locking hook, so that the rear frame is combined with the front frame rigidly and stably.

Abstract: A cover component mountable to an airbag system has a tear line that is torn open when an airbag of the airbag system inflates. At least part of the tear line includes a recessed line and hollows bored in the recessed line at intervals. The recessed line is molded into the cover component using a raised line provided on a core surface of a die, and where the hollows are bored into the cover component by laser processing.

Abstract: In a frame structure of a vehicle that includes a flywheel housing, an intermediate housing and a transmission case that are connected to each other along a longitudinal axis of the vehicle to constitute a vehicle frame, the intermediate housing has a hollow shape with a first end and a second end located along the longitudinal axis of the vehicle, the first end having an abutting surface against which the second end of the flywheel housing abuts, a support surface located radially inwardly of the abutting surface so as to support the forward/rearward movement switching unit, and an opening surrounded by the support surface, the opening serving as a first-end opening of the intermediate housing along the longitudinal axis of the vehicle. The abutting surface and the support surface along the longitudinal axis of the vehicle are located so that at least a portion of the forward/rearward movement switching unit is accommodated within the flywheel housing.

Abstract: Provided is an apparatus for establishing a caster angle of a vehicle suspension system. The apparatus includes two air reservoirs, each reservoir having an extendable piston rod. The air reservoirs are juxtaposed, and are pivotally connected to a single bell crank. In particular, the bell crank is pivotally connected to each piston rod, and to a control arm of the vehicle suspension system for establishing the caster angle. Concerted pressurizing and exhausting of the air reservoirs extends and retracts the piston rods, causing the bell crank to rotate. Rotation of the bell crank induces movement of the control arm which translates into a rotation of an axle to a desired caster angle. In one embodiment, one air reservoir is a multi-chamber reservoir capable of doubling the force used to extend the piston rod, rotate the bell crank and adjust the caster angle.
