Abstract: The invention relates to a system for attaching false stretched walls made of a flexible sheet (1) attached by the edges thereof to a mini-stringer (3?), said edges being provided with a harpoon-type hook (11) inserted as a gooseneck between the two flanges of the stringer (3?) and including a first section (11a) connected to the sheet (1) and a second section (11b) folded on the first one, and having an end bead bearing onto a shoulder (8) of the outer flange (5) of said stringer, characterised in that the end bead of the harpoon (11) includes a disconnection lip (12) extending perpendicularly from the bearing area of the bead on the shoulder (8), and extending under said shoulder (8) in the gap of the stringer (3?) so that said lip (12) can be used as a lever for urging the end of the harpoon (11) out of the shoulder (8), without any penetration of an application tool in the stringer (3?), in order to easily dismantle said sheet (1).

Abstract: An assembly includes a body of an automobile and a tailgate mounted on the body so as to be movable between an open position and a closed position. The assembly also includes: an opening assistance device mounted between the body and the tailgate in order to apply a pushing force on the tailgate that tends to move the latter into an open position; and at least one abutment provided on the body, for applying on the opening assistance device, when the tailgate is in the closed position, a force opposite to the pushing force thereof so that the tailgate is not subjected, or barely subjected, to the pushing force of the opening assistance device.

Abstract: The present invention concerns a method for designing and manufacturing a snowmobile platform. The method entails designing and manufacturing a group of tunnel subassemblies, designing and manufacturing a group of engine cradle subassemblies, and designing and manufacturing a group of front suspension subassemblies. Next, one tunnel subassembly, one engine cradle subassembly, and one front suspension subassembly are selected from each respective group. Then, the tunnel subassembly is connected to the engine cradle subassembly at a rear portion thereof. Finally, the front suspension subassembly is connected to the engine cradle subassembly at a front portion thereof to create the snowmobile platform. The present invention also concerns a snowmobile platform constructed according to this method, which combines, among other elements, a tunnel subassembly, an engine cradle subassembly, and a front suspension subassembly.

Abstract: A watercraft hull has a hull body defining a bow, a transom, and a longitudinal centerline extending from the bow to the transom along a center of the hull body. The hull body has an inner surface and an outer surface. A plurality of ribs extends at an angle to the longitudinal centerline on the inner surface.

Abstract: A watercraft bumper has an elongate body. The elongate body has a generally C-shaped cross-section. A protrusion extends from one of the end portions of the cross-section and extends towards the other end portion. A watercraft having the bumper is also disclosed. The watercraft has a lip over which the bumper is disposed. The lip has a depression formed in an upper side thereof. The protrusion of the bumper is disposed in the depression and is biased against the upper side.

Abstract: A method of indicating a deceleration of a watercraft is disclosed. The method comprises creating a spray of water using a reverse gate of the watercraft. The spray of water extends above a water level of a body of water in which the watercraft operates. The spray of water is created when the reverse gate of the watercraft is in a lowered position and the watercraft is decelerating. An alternate method comprises creating a spray of water using a reverse gate of the watercraft only when decelerating the watercraft. A watercraft for carrying out at least one of the methods is also disclosed.

Abstract: An electric grill is provided having a grate, a first electrical insulator layer located above the grate, a heater layer deposited on a top surface of the first electrical insulator layer, and a top layer located over the heater layer for protecting the heater layer.

Abstract: An inter dental device which is a tooth cleaner and gum massager which cleans the area between anterior and posterior teeth, comprising a handle and a stem and flanges and a tip which is grooved or twisted in a spiral pattern, and the flanges extending from a central stem are arranged in a spiral pattern which is continuous with the spiral pattern of the grooves of the tip. This device also may serve as a delivery device which holds and delivers substances to the area between teeth, and does not remove said substances as the device is withdrawn.

Abstract: A snowmobile having a hood releasably secured to the snowmobile via interlocking male-female members, the hood being manually releasable from the snowmobile without the use of tools. A snowmobile having a hood releasably secured to the snowmobile via a hook and elastic connector, and having fairings with a moveable section constructed and arranged to conceal or cover the hook and elastic connector.

Abstract: A marine outboard engine has an upper motor cover, a lower cover, an engine, a driveshaft, a gear case, a rotor shaft, and a bladed rotor. First and second exhaust housings are disposed in the lower cover below the engine. The second exhaust housing at least partially surrounds the first exhaust housing. A first exhaust chamber is formed by the first exhaust housing. The first exhaust chamber fluidly communicates with the engine. A second exhaust chamber is formed between the second exhaust housing and the first exhaust housing. The second exhaust chamber fluidly communicates with the first exhaust chamber. A third exhaust chamber formed between the second exhaust housing and the first exhaust housing below the second exhaust chamber is also disclosed. The third exhaust chamber fluidly communicates with the second exhaust chamber and an exterior of the marine outboard engine.
