Abstract

A bicycle saddle comprising a foam layer padding, wherein the foam layer extends over a seating area, characterized in that the foam layer is divided into segments in a region of the side walls of the seating area on the top and / or bottom.

Description

Field of the invention

The invention relates to a bicycle saddle with a foam layer.

Background of the invention

Padded bicycle saddles known from practice usually consist of a saddle shell. The saddle shell may be formed in particular of plastic injection molding or of a composite material and is usually connected to rails over which the saddle is mounted in the saddle clamping.

As a poster, a foam pad is usually used, which is covered with a fabric.

It is known to build such upholstery multilayer, in particular to use a softer foam than the uppermost layer than the underlying layer.

Foams are available in a wide variety of materials and in different degrees of hardness. Known foams, however, have in common that they are of relatively homogeneous construction and, given forces occurring, react similarly to the direction of the force, in particular to spring in a similar manner, regardless of the direction in which pressure is exerted on the foam.

However, the forces exerted on the saddle when driving are on the one hand inhomogeneously distributed. On the other hand arise by pedaling cyclically changing forces, and it would be desirable that the saddle cushion softens softer in the direction of these cyclical forces, as in another direction.

Such a different depending on the direction of the applied force hardness of the seat cushion can not be realized with conventional foams.

Object of the invention

The object, on the other hand, is to at least reduce the stated disadvantages of the prior art.

It is a particular object of the invention to make the foam pad of a saddle partially softer, preferably in dependence on the direction of the force acting on the foam pad force.

Summary of the invention

The object of the invention is already achieved by a bicycle saddle according to claim 1.

Preferred embodiments and further developments of the invention can be found in the subject matter of the dependent claims, the description and the drawings.

The invention relates to a bicycle saddle.

Preferably, it is a bicycle saddle, which comprises a front-tapered saddle nose, which merges via a transition region in a wider seating area. In the wider seating area, the user's ischial tuberosities are recorded.

The bicycle saddle includes a padding with a foam layer, wherein the foam layer extends at least over the seating area. Preferably, the foam layer extends over saddle nose, transition region and seating area.

According to the invention, the foam layer is divided into segments in a region of the side cheeks of the seating area on the upper side and / or lower side.

This is understood to mean that the foam layer is subdivided in a region near the surface.

In the simplest case, the foam layer is divided in a near-surface area to a certain depth by incisions.

It is understood that the subdivision into segments is preferably present only in the region of the side cheeks of the seating area, but not in the rest of the saddle, such as on the saddle nose.

In particular, two regions, which are subdivided into segments, extend from the outer edge of the saddle to a central region of the seating area.

The rear end of the foam layer, in particular on the rear edge of the saddle, is preferably not divided into segments.

By dividing into segments, the foam is easier to move and gives way to movement. Thus, lower pressures occur on the sit bone and on the buttocks, as without the subdivision into segments.

Due to the shape and orientation of the segments can also be achieved that the pad yields more easily when moving in one direction, as in a movement in another direction.

In particular, a saddle may be provided in which the pad yields more easily when loaded transversely to the center axis of the saddle than when loaded in the direction of the central axis of the saddle.

According to a preferred embodiment of the invention, the segments are formed by a plurality of notches.

The indentations take a certain minimum width.

The configuration of the notch again determines the shape of the segments.

The segments may have any shape, in particular, the segments may be formed as stumps delimited from one another by the notches.

The segments preferably have a flat top. Preferably, the segments taper towards the top of the foam layer.

The segments may in particular be cylindrical, cube-shaped, cuboidal or prism-shaped.

According to one embodiment, the segments are conical.

In particular, the segments taper towards the outside of the foam layer. The segments may be formed in particular as a truncated cone or truncated pyramid.

In particular, the indentations may comprise a plurality of parallel serrations which intersect with a plurality of transverse further indentations.

Thus, a regular pattern, in particular a diamond-shaped pattern, can be provided by segments.

According to one embodiment of the invention, the segments have on their surface, in particular on the surface at the edges of the segments, a degree of hardness and / or a density which does not differ substantially from the degree of hardness and / or the density in the core of the foam ,

In particular, a near-surface area to a depth of 0.5 mm has a Shore hardness A which is at most 5 higher and / or a density which is at most 20% higher than in the middle of the foam layer.

The segments are so soft especially at the edges and lead to a better yielding of the pad.

According to a preferred embodiment of the invention, the segments are formed by removing material in the region of the side cheeks of the seating area.

Thus, the segments are not formed by using a shape that dictates the contour of the segments, but are designed by a material-removing process, such as cutting or milling.

It has been found that, in particular, the edges of the segments are softer in this way. Namely, when foaming in a mold, compaction occurs in the surface portions of the foam adjacent to the mold, so that the foam hardens near the surface.

This effect can be avoided by a material removal process.

The notches may be formed in particular conical.

According to one embodiment of the invention, the segments form a check.

The segments in a preferred embodiment of the invention occupy more than 5%, preferably more than 20%, and more preferably more than 30% and / or less than 95%, preferably less than 80%, of the height of the foam layer.

The depth of the segments is defined as an average according to the invention.

According to one embodiment of the invention, the foam layer is the most resilient when loaded in one direction. This direction can in particular at an angle of 0 ° to 90 ° to the central axis of the saddle, preferably at an angle of 40 ° to 70 ° to the central axis of the saddle run.

It is thus provided in particular that the foam layer is the most flexible transversely to the central axis of the saddle.

According to one embodiment of the invention, the intermediate areas between the segments, in particular the notches, are filled with a different material than the foam layer.

In particular, the segments can be filled with a gel.

Likewise, a softer foam, in particular its hardness Shore A is at least 10 less than that of the foam layer with the segments used.

Preferably, the material with which the segments are filled, connected above the foam layer to form another layer.

This allows the other material to be applied in a simple manner, for example in a mold.

The filling of the intermediate areas makes it possible to provide a pad with a smooth contour, but still obtains the properties according to the invention, in particular the softer yielding in one direction.

The bicycle saddle may in particular in the seating area have a central recess (also called channel).

However, the segmented area preferably does not extend into the recess. Rather, preferably two laterally adjacent to the recess are divided into segments areas.

The segments may have a maximum length of more than 0.3 cm, preferably more than 0.5 cm. Furthermore, the segments preferably have a maximum length of less than 3 cm, preferably less than 2 cm.

Equal values preferably also apply to the minimum width of the segments. The seating area may have more than 10, preferably more than 20 and / or less than 100, preferably less than 50 segments.

According to one embodiment of the invention, notches extend at an angle of +/- 20 ° to the central axis, with further notches, which preferably intersect the projecting notches, extending at an angle of 30 to 60 ° to the central axis.

The segmented area preferably extends to an outer edge of the saddle and / or to a central recess.

According to a further embodiment of the invention, the segments may also be formed as a hollow body, in particular as a hollow cylinder or a hollow truncated cone.

The cavity thus formed may be filled with another material, such as a gel, a foam with other, in particular lower hardness or with a shape memory foam.

The area with the segments (see also 11 in 2 ) extends from a lateral outer edge of the caliper 8th to the middle of the seating area 4 ,

In this embodiment, the bicycle saddle includes 1 a central recess 9 , At the edge or border of the central recess 9 The areas end with the segments 6 ,

The areas with the segments 6 extend in the axial direction to the limit of the transition region 3 and ends at the back before reaching the rear edge of the saddle.

The segments 6 be through notches 7a . 7b educated.

First notches 7a are parallel to each other and substantially parallel to the central axis 16 of the saddle, in particular at an angle of +/- 20 ° to the central axis.

Second notches 7b run transversely to the central axis 16 ,

This results in a substantially diamond-shaped pattern of segments.

Since the diamonds are narrower in one direction, the padding gives in with the arrow 10 marked direction lighter than in the axial direction.

Preferably, the direction in which the cushion easiest yields is transverse, but not perpendicular to the central axis 16 ,

In particular, the direction in which the pad according to the arrow 10 easiest yielding, at an angle of 20 to 70 ° to the central axis 16 ,

The diamond-shaped segments 6 can have a point angle between 20 and 70 °.

Marked is the area 11 , in which the segments are arranged under a covering.

It can be seen that the area 11 with segments in the area of the side wall 5 extends to the saddle edge.

On the side opposite the saddle edge of the area runs 11 with the segments arcuate starting from the transition area 3 to the rear, leaving the area 11 not to the rear end of the saddle 1 extends.

The saddle 1 includes saddle rails 12 with which it can be attached to a conventional saddle clamp.

3 is a sectional view taken along the line AA the 2 ,

As shown in the sectional view, the saddle shell 13 as a carrier on which a foam layer 14 is applied.

The foam layer 14 is with notches 7 Provided.

The indentations are conical in cross-section and taper towards the saddle underside.

The notches 7 are in this embodiment with a layer 15 made of a different material, in particular with a gel layer, filled.

Preferably, the layer is of the other material 15 softer than the foam 14 , The different yielding of the padding depending on the direction of the force thus remains.

The layer of other material 15 extends in this embodiment within the range with the segments 11 over the foam layer 14 , thus forms at least between the notches 7 another layer overlying the foam layer 14 is arranged.

The padding thus formed is covered with a fabric 17 provided, which may be formed for example of a textile, leather or synthetic leather.

With the invention could be provided in a simple manner, a bicycle saddle with a padding, which is partially softer and / or which gives way differently depending on the direction of the applied force.
