A bicycle seat assembly for reducing frictional and pressure discomfort to the buttocks and urogenital region of a cyclist. The seat assembly provides for rotation of a bicycle seat about a longitudinal axis of a bicycle to accommodate the movement of the cyclist's legs and hips while pedaling. The assembly may also provide for rotation of the seat about a vertical axis to provide additional relief of frictional and pressure discomfort.

The invention includes apparatus and methods of use for an adjustable disarticulated seat, which in a preferred embodiment may include one, or a plurality of independently or synchronously adjustable disarticulated inserts positioned within insert interface apertures on the distal extended portion of a saddle. An actuator element may be responsive to the one or more disarticulated inserts through one or more cords configured to be retracted or release in response to the action of the actuator causing the extension upward or release downward movement of the one or more inserts within the insert interface aperture.

A bicycle saddle includes: a base structure having a top portion; and a cushion coupled to the top portion of the base structure, the cushion including a first lateral side and a second lateral side separated by a longitudinal plane, wherein each of the first lateral side and the second lateral side includes: a first region having a first stiffness; a second region having a second stiffness that is less than the first stiffness; and a third region having a third stiffness that is less than the second stiffness, wherein a perimeter of the second region is at least 75% enclosed within the first region, and wherein a perimeter of the third region is at least 75% enclosed within the second region.

A system for biomechanical analysis of user posture and automatic customized manufacture of bicycle parts includes a servo-assisted simulator having a handlebar, a saddle, pedal cranks, and actuators, a device detecting input data that includes a 3D scanner for automatically detecting the position of body segments of the user and the angular ranges therebetween and generating three-dimensional physical data units, an electronic platform detecting pressure data of the user, a pair of insoles detecting plantar pressure, a computer connected to the actuators and to the detection device, a memory unit storing optimized initial data and instantaneous data, software comparing the optimized initial data and the instantaneous data and generating final data of the characteristics of the main parts, a spatial representation device spatially representing the final data, and a device for immediate manufacture of the parts using 3D printers. A method of biomechanical analysis and custom manufacture of bicycle parts.

A split-nose touring bicycle seat for touring, comprising: a rigid plastic base provided with attachment points for mounting the seat to a bicycle frame; a total length of the seat of about 230-265 mm; a total width of about 270-310 mm; a split nose section formed by two elongated protrusions of substantially constant width extending forward from a medial section to a front surface; said elongated protrusions angle inwardly, a cushioned pubis bone support surface with a substantially flat side profile, and a drooped nose section forward thereof and substantially vertical outer sides.

An adjustable-width saddle includes a frame having a forward end and a rearward end, the rearward end including a laterally extending bridge, and a one-piece shell. The one-piece shell includes a forward end connected to the forward end of the frame, and a split rearward end including a first rider support and a second rider support that are supported at least in part by the bridge. The rider supports are laterally separated from the second rider support by a lateral gap that is adjustable by flexure of the one-piece shell. A lower side of each rider support defines a first channel that receives the bridge. Fasteners extend through one or more slots formed through the bridge and engage the rider supports to fix the gap at a selected width.

A shell for a bicycle saddle has a groove opened through top and bottom surfaces thereof, a narrow anterior portion having a front edge, and a wide posterior portion having a rear edge and divided by an imaginary longitudinal axis passing through the front and rear edges and the groove into left and right regions where two sockets are located, respectively. The groove has a longitudinal section extending along the axis, and a transverse section extending from a rear end of the longitudinal section to the left and right regions so as to form two elastic wings adjacent to the groove. Each socket has a connecting sheet and an insertion block and extends from rear and lateral edges of the wide posterior portion to a position under the bottom surface to form a space therebetween. As a result, the shell has great elasticity and structural strength.

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.

An adjustable seat assembly for a motorcycle has a seat pan and an adjustment mechanism. The seat pan includes a base portion and two pivoting portions that are pivotally connected to the base portion and are arranged laterally adjacent to one another on the base portion. The base portion has a fastening portion for fastening the seat assembly on the motorcycle. The adjustment mechanism is designed to pivot each of the two pivoting portions in relation to the base portion to adjust a lateral width of the seat assembly. A motorcycle with an adjustable seat assembly is also provided.

Method and apparatus for improving mobility in patients affected by a neurodegenerative disease, through controlled and localized mechanical stimulation of the foot, at the tip of the big toe and the lower big toe metatarsal joint. Described herein is an apparatus comprising stimulators for the right and left foot and it attains such mechanical stimulation according to predetermined intensity parameters, stimulation sequence, duration and cyclical repetition. Mobility improvement was observed in particular in patients affected by Parkinson's disease.
