Embodiment Construction

[0025] Specifically referring to the above drawings, the method for making an integral elastic support according to the present invention will be described. The overall elastic support is indicated by the numeral 1 as a whole. Various supports 1, such as seats, seat backs, armrests, saddles and seats for bicycles and similar vehicles, can be obtained in the manner described below.

[0026] In more detail, each support 1 comprises a substantially rigid or semi-rigid shell 2 and at least one layer 3 of elastic filler. A sheath 4 designed to be accessible to the user may be provided. The cover 4 defines a contact surface 4' for the user. Alternatively, the padding layer 3 with a suitably finished surface may directly define the user's contact surface 4'.

[0027] The method of the invention comprises a first step a) forming a casing 2 having a predetermined shape and structure. In a second step b), a model 5 is created for forming the filler layer 3 on the shell 2 . For this...

Abstract

A process for making integral elastic supports, such as chair seats, seat backs, arm rests, bicycle saddles and vehicle seats and the like, including the following steps: a) making a shell (2) with a predetermined shape and structure; b) setting up a mold (5) with at least one inner cavity (6) and capable of being moved from an open condition to a closed condition; c) introducing at least one foamable resin and the shell (2) into the inner cavity (6) of the mold (5); d) foaming the resin to form a filler layer (3) to be joined to the shell (2) into a single assembly (7); e) removing the assembly (7) from the mold (5). In greater detail, the shell (2) is manufactured in a first step a1) for making a main body (8) having a peripheral edge (9) and a second step a2) for making a sealing member (10) in the proximity of the peripheral edge (9), to essentially close any gap between the shell (2) and the inner cavity (6) in the proximity of the peripheral edge (9) and prevent the formation of burrs as the foamable resin is foamed.

Description

technical field [0001] The invention has general application in the field of human body support and relates in particular to a method for making integral elastic supports and supports obtainable by such a method. [0002] The support according to the invention can advantageously be used as a part of the structure of vehicles such as bicycles and motorcycles, but also furniture such as seats and backs, stools and the like. Background technique [0003] Many embodiments of bicycle or similar vehicle saddles have a substantially rigid shell and a flexible sleeve that defines the saddle surface. Also, one or more layers of resilient filler are typically interposed between the sleeve and the housing. [0004] Patents US-A-6066277, US-A-2003164629, WO-A-9937459, disclose similar methods for making saddles. The method comprises a molding step of at least one filler layer. In particular, each method provides the existing structure of the rigid shell and guides it into the model. ...
