Abstract

The invention relates to a bicycle saddle, comprising a saddle shell fastened to a seat post, the saddle having a front part, which merges into a wider rear part, which forms a seating area, wherein the rear part has two recesses in the region of the seat leg bumps of a user.

Description

Field of the invention

The invention relates to a bicycle saddle, which is fastened by means of a seat post on the seat tube of a bicycle.

Background of the invention

Bicycle saddles, as they are used for all types of bicycles, including electric bikes, are usually mounted vertically adjustable by means of a seat post on the seat tube of the bicycle frame.

For this purpose, a seat post is provided, which can be pushed into the seat tube and fixed there.

Saddles known from practice often comprise a saddle shell, on the underside of which saddle struts are attached. These saddle struts are usually attached to the saddle nose and the saddle ends and are anchored with a saddle clamp on the saddle head, which in turn is connected to the seat post.

In practice, an arrow-shaped saddle shape has prevailed, in which the saddle has a narrow front part, which passes over a transition region in a wide rear part. The user's ischial tuberosities are located on a rear portion of the saddle that forms a seating area. In saddles known in practice, it is usually the goal to achieve a uniform pressure distribution in the region of the ischial tuberosities. For this saddles in various widths are available in practice, in which the seat portion of the saddle has two cambers on which the buttocks of the user rest. By usually padded bearing surfaces and a good fit for each user's saddle width as uniform as possible pressure distribution should be achieved.

Object of the invention

The invention is compared to the above-described prior art, the object to further improve the ergonomics of a bicycle saddle.

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 invention relates to a bicycle saddle, as this for all types of bicycles, including so-called e-bikes, can be used.

The bicycle saddle includes a saddle shell attachable to a seat post, the saddle having a saddle nose that merges into a wider seat area.

The bicycle saddle consists in particular of a narrower front part, which merges in a central part in the wider seating area, on which rest the ischial tuberosity or covered with skin and tissue of the patient's ischial tuberosity.

The bicycle saddle can be connected to a seat post on the underside via the seat stays.

In particular, the bicycle saddle may comprise the saddle strut system described above, ie struts which are connected to the saddle shell and are secured to the head of the saddle post in the saddle clamp.

According to the invention, the rear part of the saddle in the region of the ischial tuberosity of a user on two recesses.

By recesses in the region of the ischial tuberosities is meant a design of the saddle in that the user's ischial tuberosities can sink into the recesses, so that the buttocks of the user are supported by the material extending around the recesses.

The recesses are formed in particular as recesses of a saddle shell and / or a saddle core made of an elastic material.

In one embodiment of the invention, the saddle is formed at least two layers and comprises a saddle shell, which is in particular made of wood or plastic, as well as a saddle core, a layer of elastic material, e.g. Foam, which is arranged on the saddle shell.

Preferably, both saddle shell and saddle core extend from the saddle nose to the seating area.

The saddle core may in particular consist of a closed-cell foam. In particular, a PU or silicone foam is used. The foam preferably has one Density from 150 to 250, more preferably from 180 to 200 g / l.

The saddle shell is preferably formed of a non-porous material and is preferably made of a thermoplastic. Preferably, the saddle shell is produced by means of an injection molding process.

The recesses preferably extend through both the elastic material and the saddle shell.

In one embodiment of the invention, the recesses are at least partially free of any elastic material.

It is understood that for the purposes of the invention, the effect described above can also be achieved by the recesses with a material, e.g. a foam which is softer than an adjoining material of the saddle core.

Thus, in a further embodiment of the invention, the recesses are filled with a gel or with a softer foam. In particular, a foam with a density of at least 30% compared with the foam of the saddle core can be used for this purpose.

In a further development of the invention, the two recesses are covered with a fabric. It is particularly provided to span the recesses, which are present in a saddle shell or a saddle core, with an elastic sheet. This may be, for example, a textile fabric, such as a fabric or a nonwoven. It is particularly contemplated to use a soft elastic material, such as e.g. Sponge rubber, to use. Preferably, the elastic sheet is spaced from a string of the saddle.

It is provided in particular that the bicycle saddle comprises a saddle shell with recesses, which are spanned by the elastic fabric. Then follows an ergonomically shaped foam core as a saddle core, which also has recesses and which is provided with a covering which serves as a seat.

The elastic sheet can be used, in particular, as a relatively thick material with a thickness of more than 1 mm. In particular, it is provided to use a sheet in a thickness between 1 and 8 mm.

The ischial tuberosity of the user, in particular, when the recesses are covered with a sheet, as resiliently supported in a hammock. This significantly improved the ergonomic comfort of the saddle.

In contrast to the known bicycle saddles described above, the invention further achieves that forces which push the ischial tuberosities outwards are largely avoided. Rather, the pelvis of the user is supported by a compression of the ischial tuberosity. It is therefore no longer sat on the ischial tuberosities or on the pubic rams, but the ischial tuberosens are relieved by the contact with the saddle is made predominantly or exclusively by the gluteal muscles. This prevents a spreading of the pubic bones. This relief of the ischial tuberosity and pubic bones reduces pressure peaks in these areas and instead distributes them into the gluteal muscles.

The ischial tuberosities, which consist of bone tissue, can swing through and the user is predominantly supported by the gluteal muscles. Furthermore, the user's pelvis is also supported in the neck area of the femoral neck.

The recesses are preferably formed at least on the upper side as substantially oval indentations.

Furthermore, the recesses preferably have a main direction of extension, i. There is a direction in which the recesses are longer than in the other direction. In this respect, a length and a width of the recesses are defined. The length is preferably at least 1.25 times the width of the indentation.

Length and width are measured according to the invention to the point at which the saddle or the saddle core begins to sink, so start at which recesses.

Preferably, the edge region of the recesses is rounded and / or has oblique side walls.

As a result, as is provided in a preferred embodiment of the invention, from the top to the bottom of the surface area of the respective recess to less than 0.8 times, preferably less than 0.7 times smaller. Furthermore, the preferably oval or slot-like recesses extend in such a way, that these run towards each other in the direction of a middle part of the saddle.

The angle at which intersect the central axes of the recesses, in one embodiment of the invention is 60 to 140 °, preferably 80 to 120 °.

The recesses have at the top of the saddle shell and / or the saddle core according to an embodiment of the invention, a width of 25 to 45, preferably from 30 to 40 mm and / or a length of 60 to 100, preferably from 70 to 90 mm.

Furthermore, the saddle, in particular a foam core of the saddle, is preferably ergonomically shaped such that the surface increases towards a rear side of the saddle, in particular by at least 0.5 cm.

Further, the recesses in the plan view, ie at the top of the saddle base, preferably have a surface area of 18 to 35, preferably from 20 to 28 cm ² .

In a preferred embodiment of the invention, the saddle comprises a saddle shell on which a three-dimensionally shaped layer of elastic material, in particular of foam, is applied as a saddle core.

The saddle shell is preferably itself already ergonomically shaped or has at least regions of different heights, which are adapted to the loads occurring in the respective region of the bicycle saddle.

Preferably, the saddle shell is not inclined downwards from the perspective of the frontal plane. In conventional saddles, the middle is usually higher than the sides of the saddle shell.

In a preferred embodiment of the invention, however, the saddle shell is shaped from the perspective of the frontal plane such that the center of the saddle shell is lower than the sides of the saddle shell.

In a further embodiment of the invention, which is provided in particular for racing saddles, the saddle is formed in one piece and is optionally spanned only with a reference. It is understood that the cover also elastic sheet, e.g. made of foam, can cover upholstery.

According to one embodiment of the invention, the bicycle saddle has a width of 15 to 28 cm, preferably 16 to 23 cm, particularly preferably 19 to 22 cm, and / or a length of 20 to 28 cm, preferably 22 to 26 cm.

The width of the bicycle saddle is determined by the width of the seat area. The length is defined as the beginning of the narrower front part to the end of the seating area.

In a further development of the invention, the bicycle saddle comprises on its upper side in the dam area of the user a further recess. This recess preferably extends only through the saddle core, provided that the saddle is constructed in multiple layers.

This avoids that pressure arises in the sensitive dam area.

The seating area of the saddle preferably includes a central depression.

The invention further relates to a bicycle comprising a bicycle saddle as described above.

In a further development of the invention, the bicycle saddle is connected via an elastic damping element with the seat tube of the bicycle.

Such a damping element can be installed, for example, below the saddle shell, in particular in the region of the saddle clamp. Preferably, the damping element allows at least one force-dependent tilting of the saddle. The damping element is preferably below the saddle, in particular approximately below the middle of the saddle, based on its length.

In conjunction with the saddle formed according to the invention, shear forces, which displace the skin when driving compared to driving, are thereby reduced in particular.

The saddle follows the movements of the user, which in particular also the fatigue of the user is reduced, since it must counteract the forces occurring less.

Detailed description of the drawings

1 is a perspective view of a first embodiment of a bicycle saddle according to the invention 1 without stringing.

The bicycle saddle shown here 1 is still provided with a fabric, such as leather or synthetic leather.

The saddle 1 is formed in this embodiment, multi-layered.

In the view according to 1 is the top 2 of the bicycle saddle 1 to recognize.

The bicycle saddle 1 includes a narrow front part 3 which is in a middle area 4 in a wide rump 5 passes.

The rump 5 is through a sink 8th divided into two halves. The sinking 8th is preferably between 1.5 and 2.5 cm deep and serves to sink the sacrum.

From the end of the front piece 3 Starting from the center area 4 a central recess 9 until about the middle of the buttock 5 , About this recess 9 sits the dam area of the user.

According to the invention comprises the bicycle saddle 1 two recesses 6 ,

The recesses 6 are oval or slot-like or egg-shaped and extend on both sides of the rear part 5 pointing to the middle part diagonally backwards.

The recesses 6 are in the edge area 7 bevelled or rounded. As a result, the area of the recesses tapers 6 towards the bottom of the saddle 1 ,

In an embodiment of the invention, not shown, the recesses 6 for the ischial tuberosities also in the central recess 9 go over to the perineal area, leaving the transition area 17 are also sunk.

2 shows the in 1 illustrated saddle 1 in a side view.

Good to see in this view is that the saddle 1 multi-layered structure.

In this embodiment, the saddle includes 1 a saddle shell 11 , which preferably consists of plastic.

The saddle shell 11 forms the bottom of the saddle 1 ,

At the saddle shell 11 are saddle struts 10 attached, which are attached to the saddle head (not shown).

Next includes the saddle as a saddle core 13 an ergonomically shaped layer of elastic material, in particular of a foam, which is provided with a covering and then serves as a support surface for the user.

It can be seen that in the area of the hindquarters 5 the elastic material 13 (except in the area of the central depression 8th ) thickened, hence the saddle core 13 rises to the rear.

The saddle core 13 is preferably 1.5 to 2.5 cm high (based on the thickest point) in the front region.

In the rear area is the saddle core 13 preferably 0.5 to 1.5 cm higher than in the front region formed.

It can also be seen that in this embodiment, the saddle shell 11 is not designed as a flat plate of uniform thickness, but that this in the area of the rear part 5 is thicker.

Preferably, the surface of the saddle shell follows 11 from their topography of the surface of the saddle core 13 but is preferably flattened in height but opposite the saddle core, in particular by at least 30%.

Between the saddle core 13 , So in particular the foam layer, and the saddle shell 11 , there is another layer in the form of a sheet 12 , In this embodiment, it may be a few millimeters thick foam rubber layer.

It is understood that as a sheet 12 but also other materials, in particular textile materials, come into consideration.

By the between the elastic material 13 and the saddle shell 11 existing fabrics 12 are recesses, which also the saddle shell 11 through, through the fabric 12 spans.

The fabric 12 acts much like a hammock and allows a resilient sinking of the ischial tuberosity of the user.

A similar effect can additionally or exclusively by the covering of the saddle 1 be achieved.

3 is a perspective view of an embodiment of the saddle core 13 ,

Evident are the substantially oval-shaped recesses 6 , which have a main extension direction, through which a respective central axis 21 is defined.

It is understood that the single recess 6 is not designed exactly mirror-symmetrical.

It can be seen that the recesses 6 each increase in a rear area and that the surface area of the recess decreases from the upper side toward the lower side.

The central axes 21 preferably intersect at an angle α of 60 to 140 °, preferably from 80 to 120 °.

It is understood that in the not exactly symmetrical recesses 6 the midlines are approximated.

According to the invention, the length 1 and the width b by the length and width at the top of the respective recess 6 Are defined. Length and width decrease towards the bottom.

The recesses 6 have in this embodiment, a width b of 30 to 40 mm and a length 1 from 70 to 90 mm.

Furthermore, the inclined recesses preferably extend over a length of the saddle of 55 to 70 mm.

The width of the saddle in this embodiment is 20 to 22 cm.

Preferably, the centers of the recesses 60 to 130, more preferably 80 to 110 mm apart. The centers are defined as the centroids of the surface of the recess.

In one embodiment, not shown here, the recesses are filled with a soft against the saddle core foam or a gel. These fillings preferably each have a volume between 25 to 50 ml, more preferably 30 to 40 ml.

4 shows a view on the bottom 14 a bicycle saddle, in which the in 1 and 2 described saddle with a string 15 is provided.

It can be seen that also the saddle shell 11 two recesses 6 has, which are formed oval in this exemplary embodiment.

The recesses 6 the saddle shell 11 are therefore designed as passage openings and are preferably open at the bottom.

The recesses of the saddle shell 11 starting from the underside, starting first from the fabric ( 12 in 2 ) and then from the fabric 15 spans.

Further to recognize are those on the saddle shell 11 existing three shots 16 through which the seatposts 10 being held. These are the two rear seat stay mounts and the front seatpost stay. The design of the saddle struts 10 corresponds to a conventional saddle. This is how the saddle struts run 10 front together and are attached side by side in a receptacle, whereas the saddle struts 10 spaced apart from each other in two seats. The saddle frame, which is made of the saddle struts 10 is formed, is formed as a bent tube which is bent symmetrically in the center in the region of the front receptacle.

5 shows the in 4 illustrated bicycle saddle 1 seen from the top.

By covering the recesses are barely visible.

6 shows an alternative embodiment of a saddle 1 , which is especially intended for racing bikes.

In contrast to the previously described embodiment of a bicycle saddle is the saddle 1 not multilayered with an ergonomically shaped layer of foam.

The saddle 1 consists essentially of a plastic saddle shell, which the slot-like recesses 6 in the rump 5 having. The saddle 1 can be designed either as a saddle shell with a molded foam cover or as a saddle shell with a coating of a sheet, in particular made of artificial leather. Preferably, this embodiment of a saddle is thus formed in two layers.

7 shows by means of a functional model, such as a saddle according to the invention 1 via a damping element 18 with the seat post 19 connected is.

The damping element may be divided into a plurality of damping elements in a further embodiment, not shown here, for example by these on the recordings of the saddle struts ( 26 in 4 ) are located.

In this embodiment, the saddle shell comprises 11 the plate 16 , which via a damping element 18 with the plate 20 connected to which the saddle struts 10 for attaching the saddle to the saddle clamp 22 are attached.

Through the damping element 18 become force-dependent tilting of the bicycle saddle 1 and preferably also allows twists.

In combination with the inventively designed bicycle saddle 1 With recesses in the region of the ischial tuberosity increased comfort and improved performance of the cyclist is achieved, as a natural pelvic movement is allowed.

The seat post 19 is attached in a conventional manner to the seat tube of the bicycle, for example by means of a seat post clamp.

A similar effect can, as in 8th represented, also by a sleeve-shaped damping element 24 be reached, that between the pipe 23 the seat post and a bolt or tubular end 25 the saddle clamping 22 is set.

The saddle clamping 22 to which the bicycle saddle can be tightened, so both in the longitudinal and transverse direction can be tilted as well as around the axis of the tube 23 twistable.

9 is a schematic diagram, based on which in particular the design of the saddle shell 11 easy to recognize. In a sectional view along a plane parallel to a frontal plane, the saddle shell is shaped like a bowl. The middle of the saddle shell is preferably at least 0.5, more preferably at least 1 cm lower than the edges (relative to the top of the saddle shell 11 ).

The ischial tuberosity of the driver can pass through the recesses 6 sink in and the driver is supported by the surrounding muscles.

Referring to 10 to 12 is a further embodiment of a bicycle saddle according to the invention 1 be explained in more detail.

10 is a perspective view of the bicycle saddle 1 without stringing. In this view is the saddle core 13 to recognize which may consist of a soft material, in particular of a foam.

11 is a view of the underside of the saddle 1 ,

You can see that the saddle shell 11 the recesses 6a in the rear part 5 having.

Next, this embodiment has a further recess 9 in the dam area of the driver.

12 is an exploded view of the saddle.

It can be seen that the recesses 6a of the saddle shell 11 not open, but with a plate 27 be closed.

The plate 27 consists of a softer material than the rest of the saddle shell 11 and thus allows a compression of the ischial tuberosities in the region of the recesses 6a.

It can also be seen that also the saddle core 13 Recesses 6b has. The recesses 6b are not formed as through holes, but as wells and serve to receive inserts 28 made of a different material, in particular a softer foam, than the rest of the saddle core 13 or a gel.

The stakes 28 sit in the trough-shaped recesses 6b of the saddle core 13 ,

It is understood that the saddle also a string (not shown), which preferably over the entire saddle core 13 is drawn.

In this embodiment, the driver's ischial tuberosity may be due to both the softer inserts 28 as well as due to the in this embodiment with the plate 27 closed recesses 6a of the saddle shell 11 deflect.

According to further alternative embodiments, which are not shown here, the recesses 6a can not be closed with a plate, but be open at the bottom, so that the saddle core 13 can spring into the recesses 6a. Further, according to another embodiment, it is also conceivable that only the saddle core 13 the recesses 6b, the saddle shell 11 but not provided with the recesses 6a.
