A seat belt loop system for use with an animal/pet carrier in order to transport an animal in a moving vehicle. The seat belt loop system includes an anchor tab coupled to the pet carrier, a cinch strap coupled to the anchor tab, and cinch strap with a proximal end coupled to the pet carrier and a distal end for insertion through the cinch loop. Once inserted, the distal end is cinched against the cinch loop and then coupled to the cinch strap. A fastening mechanism on the cinch strap is engaged to retain a vehicle seat belt between the pet carrier and the seat belt loop.

A belt fastener assembly for fastening belt ends together comprises: first and second retention plates receiving and retaining substantially abutting belt ends between the plates, and defining a plurality of bolt holes. A plurality of threaded bolts each extend through a bolt hole of each of the first and second plates and also extend through portions of the belt positioned between the plates, to retain the first and second plates and the belt ends together, with nuts carried on the bolts. Washers are also carried on the bolts, each having an aperture and having, in an original condition prior to use, a frustoconical inner area surrounding the aperture to enlarge the aperture to a size of at least the outer diameter of the bolt threads. This facilitates placement of the washers on the bolts. Then, the washers may be flattened to decrease the size of the apertures, to retain the bolts in position extending through a retention plate prior to full assembly.

The present invention is directed to a treadmill belt with foamed cushion layer and method of making same. In one embodiment, the treadmill belt includes a fabric base layer and a foamed cushion layer foamed on and integral with the fabric base layer. The foamed cushion layer includes a thermoplastic composition and has a Shore A hardness of about 20 to about 80.

An outer wear layer is securely adhered on the foamed cushion layer to sandwich the foamed cushion layer between the fabric base layer and outer wear layer thereby defining the treadmill belt.

A production method of a decorative film comprises a first step of laying a base film of a thermoplastic resin on a pattern layer of a transfer sheet in which the pattern layer is placed on one surface of a carrier film, thermally transferring the pattern layer onto the base film, and thereafter stripping off the carrier film, thereby obtaining a laminate sheet in which the pattern layer is placed on one surface of the base film; and a second step of, in a state in which a transparent resin film is laid on a surface of the laminate sheet on the pattern layer side, inserting the laminate sheet and the transparent resin film into between a pair of endless belts placed opposite each other, and conveying the laminate sheet and the transparent resin film under heat and pressure, thereby obtaining a decorative film in which a transparent resin layer of the transparent resin film is placed on the surface of the laminate sheet on the pattern layer side.

A belt clamping system including an open-ended, flat belt with an end portion having a number of teeth projecting therefrom and a clamping plate with matching tooth profile for use in connecting the belt end to another structure. The flat belt may be reinforced with longitudinally extending cords. The toothed profile may be a standard timing belt profile and may be unreinforced. A length of timing belt profile material may be welded to the flat surface of the open-ended flat belt at or near an end. The length of timing belt profile may include at least 7 tooth pitches. The end portion may be clamped between a flat surface of a flat plate and a grooved surface of a grooved plate having grooves complementary to the timing belt teeth.

A method for enabling a presetter to connect connecting portions of belts having different widths, and for forming an endless connection of a flat belt with no defects such as the bend of the connecting portions. This method includes a first step of setting so that the connecting portions at both ends of the flat belt are placed on a lower mold surface of the presetter, and that, with the flat belt held from both sides by a wall part standing from the lower mold surface and a flat belt member having substantially the same compression property as the flat belt, an upper mold of the presetter is placed on the flat belt and the flat belt member, and then fixing the flat belt and the flat belt member by the presetter; and a second step of connecting the connecting portions at the both ends by pressing the presetter with the flat belt and the flat belt member fixed.

A safety belt system especially for a passenger chair has at least one, preferably two, safety components each of which includes a controlled flexibility. The controlled flexibility is provided by a relatively stiff sheath or whip or belt section. A limp belt member passes through the sheath with the controlled flexibility. In a second embodiment, the controlled rigidity is provided by a flexible belt end section. In both embodiments one end of each safety component is secured to the chair and the other end has a belt lock element for closing the belt system for use. In an open rest position at least one, preferably both, safety components rest against the backrest of the chair. The controlled flexibility provides a spring biasing force that keeps the safety component in the rest position from which the passenger can turn the safety component into a use position and close the system with one hand.

A V-ribbed belt for a mechanical power transmission is disclosed. The V-ribbed belt comprises an outer back-side surface, an inner front-side surface, and a load-carrying section disposed between the front-side and back-side surfaces. The front-side surface includes a plurality of laterally spaced longitudinally extending v-ribs. The back-side surface includes a plurality of raised features that, when running on a flat-faced, back-side pulley, form a contact patch of about 20% to about 50% of that of a traditional flat-faced belt running on a flat-faced pulley. The reduced contact patch provides increased contact pressure which in turn provides an improved effective coefficient of friction between the belt and the pulley.

An electric actuator comprises a rotary driving source, a timing belt which is circled or orbited under the driving action of the rotary driving source, a slider which is displaced by the timing belt in the axial direction, and a belt-adjusting mechanism which is connected to a side surface of the slider. Both ends of the timing belt are connected to the belt-adjusting mechanism respectively. The tension of the timing belt is adjusted by rotating an adjusting screw of the belt-adjusting mechanism.

A belt member is formed with a seam portion by overlapping and adhering both longitudinal end portions thereof to constitute an endless belt stretched and circulated by a rotative, first stretching member and a second stretching member. A length of the seam portion is no less than a length between a first point at which the endless belt is separated from one of the first stretching member and the second stretching member and a second point at which the endless belt is brought into contact with the other one of the first stretching member and the second stretching member.

A splice joint is for joining first and second synchronous drive belt ends, of the belt type comprising a reinforcement material layer covering a base layer formed from a first thermoplastic material. The joint comprises a fused portion of the base layer of the first and second belt ends that define a splice region. At least one coating layer of thermoplastic material overlaps the reinforcement layer of the end portions in the splice region. The coating layer is comprised of a second elastomeric material intended to melt and penetrate into interstices of the reinforcement material layer while within the mold press. Migration of the base layer material through the reinforcement material layer to the pulley-engaging outer surface is thereby inhibited. The second elastomeric material composing the coating layer may be selected to provide desired frictional and wear characteristics.
