A leather bicycle saddle includes a leather cover, an arc support supporting the leather cover and having a front end terminating in a head abutment portion and a rear end affixed to a rear bottom side of the leather cover, and an adjustment device including a screw bolt holder affixed to a front bottom side of the leather cover, an adjustment screw bolt abutted against the screw bolt holder. The adjustment seat includes a seat block defining a mounting slot and a screw hole, and a stop block. The stop block is engaged into the open end of the mounting slot and stopped at the head abutment portion of the arc support against the close end of the mounting slot. The screw hole of the seat block receives the adjustment screw bolt.

The purpose of the present invention is to provide a cushioning material structure, for a vehicle seat, that makes it possible to reduce the weight of the vehicle seat while maintaining stable riding performance. A cushioning material supported by the top surface of a bottom plate provided on a vehicle body is provided with voids. This allows weight reduction without reducing the thickness of the cushioning material as in conventional cushioning-material structures, thereby making it possible to reduce the weight of the vehicle seat while maintaining stable riding performance.

An assembly composed of a saddle (10) and of a saddle compartment (12) for a motorcycle is described. The saddle (10) comprises an upper padded portion which constitutes the seat for the rider and/or passenger of the motorcycle, and a substantially rigid bottom portion (14) operatively connected to the relative saddle compartment (12) by hinge means (16). The saddle compartment (12) is made integral with a fixed portion of the motorcycle. The hinge means (16) enable the saddle (10) to pass from a closed position, in which said saddle (10) is positioned substantially horizontally above the saddle compartment (12) and permits the rider and any passenger of the motorcycle to sit on it, and an open position, in which said saddle (10) is positioned in a substantially vertical position and permits access to the saddle compartment (12). The assembly comprises at least one gas spring (18) attached to a fixed portion of the motorcycle and operatively connected, at its upper end, to the saddle (10). Between the upper end of the gas spring and the saddle (10) articulated connection means (20, 22) are interposed which permit said saddle (10) to maintain a stable open position.

A bicycle seat apparatus including at least one rail and a saddle shell. The at least one rail can include a first mounting portion. The first mounting portion can include an ankle. A cross section of a terminus of the ankle can be larger than a cross section of the at least one rail. The saddle shell can include at least one mounting cup configured to mate with the first mounting portion of the at least one rail. A cross section of a base of the at least one mounting cup can be larger than a cross section of the terminus of the ankle.

A bicycle seat can include an attachment structure configured to be secured to a bicycle frame. The seat can also include a support frame, which can include right and left arms extending laterally out on opposite sides of a vertically-oriented medial plane of the bicycle seat. The seat can include walls, which can include a front wall and a rear wall that extend up and laterally out from the attachment structure to support the right and left arms. Right and left seat pads can be selectively securable to the right and left arms, and can be adjusted between different positions relative to each other. Each seat pad can include a main pad portion that is secured to the corresponding arm and is configured to provide upward support to a corresponding ischium (sometimes referred to as the sit bone) of the rider, and an elongate extension that can extend laterally out and forward beyond the main pad portion.

A seat cushion includes an edge portion and a three-dimensional fiber structure including core-sheath fusible fibers and skeletal fibers thermally fused at intersections thereof. The sheaths of the core-sheath fusible fibers are made of a thermoplastic elastomer to fuse the intersections and form a bulging portion at each of the fused intersections. The skeletal fibers and the cores of the core-sheath fusible fibers are made of a non-elastomer resin. The skeletal fibers are crimp-processed bulky fibers, and a fineness of the skeletal fibers and a fineness of the core-sheath fusible fibers are in a range of 1 to 200 dtex. The seat cushion has a layered structure including a plurality of layers fused together, each of the layers has the three-dimensional fiber structure, and the seat cushion has a density distribution based on regional variations of the layered structure and a stiffness distribution that depends on the density distribution.
