- the state of the art is an unsuspended saddle or a mostly saddle frame with suspended metal springs or a saddle with a pneumatic spring arranged on the upper part.
- the disadvantage of this construction is insufficient seating comfort.
- the disadvantage of the metal springs is a predetermined spring force, a complicated construction and a great weight.
- the pneumatic springs on the upper part of the saddle offer a softer ride but cannot absorb the bumps that are transmitted from the firmer to the softer parts of the body.
- the invention is therefore based on the object of creating a pneumatically sprung saddle which, in the preamble of claim 1, creates the type which avoids the disadvantages mentioned above.
- the object on which the invention is based is achieved in that a pneumatic spring with at least one valve is attached in the inner space of the lower side of the saddle skeleton, and at least one guide element of a guide mechanism is provided on the lower side of the saddle skeleton, the saddle skeleton using the pneumatic spring and the guide mechanism are movably connected and guided at the same time with a saddle bracket, the predominantly central part of the saddle bracket forming a wing which is supported against the lower elastic part of the casing of the pneumatic spring and pressed into its inner space in a loaded state is.
- Another advantage is a universal mounting on the bicycles and a low weight of the saddle, the possibility of any shape of the upper seat part of the saddle the same as with a usable one
- Suspension mechanism is arranged in the inner space.
- the pneumatic spring forms a closed pressure chamber where it is not necessary to seal the mutually moving parts.

- FIGS. 7, 8 and 9 Another exemplary embodiment is shown in FIGS. 7, 8 and 9, where the guide element of the guide mechanism L, with which the saddle skeleton 2 is slidably guided on the saddle bracket 1, is designed as at least two guide V surfaces L7 leading down from the saddle skeleton 2 is.
- each guide V surface L7 is determined from the outside by a saddle guide L6 attached to the lower side of the saddle skeleton 2, and from the inside by a bracket guide L5 forming part of the saddle bracket, the guide V surface L7 consists of two side surfaces forming a smaller angle than 180 ° to one another and the intersection of the side surfaces of a guide V surface L7 lies in a plane which is parallel to a vertical axis plane determined by the elongated horizontal and the vertical saddle axis, with the lower one
- each guide V surface L7 after one Radius is curved, the center of which lies on an auxiliary axis arranged perpendicular to the vertical axis plane and the plane leading through the radius of curvature is parallel to the vertical axis plane, the auxiliary axis for the guide mechanism L of the saddle being common for all radii of curvature of the guide V-surfaces L7 and is arranged forward from the guide mechanism L.
- the saddle guides L6 have a position ⁇ .
- FIGS. 10, 11 and 12 Individual structural elements of a further exemplary embodiment in FIGS. 10, 11 and 12 are shown in detail in FIGS. 13 to 22.
- at least one substantially vertical closed guide groove 21 is provided, in which a front end of the saddle bracket 1 is guided with at least one horizontal guide pin 11.
- a vertical axis plane of the saddle skeleton C2) is determined by the horizontal longitudinal axis and by the vertical axis of the saddle skeleton C2 ) , two guide walls 22 parallel to the vertical axis plane of the saddle being provided in the rear part on the inner lateral sides of the saddle skeleton, with lower displacements in the form "L" with which the lateral surfaces of the guide arms 12 of the rear end of the saddle bracket 1 are guided and the middle upper part of the saddle bracket 1 is supported against the lower elastic part of the casing of the pneumatic spring 3 and the lower part of the saddle bracket 1 is adapted for attachment to the seat post.
- the inner side of the saddle skeleton 2 is predominantly straight in the contact point with the pneumatic spring 3 and the upper side of the saddle skeleton 2 is provided with at least one stiffening rib 25, which is covered from above with a soft seat layer.
- the saddle bracket 1 is designed as an injection molding, which is provided in its front part with a projection, at the front end of which at least one horizontal guide pin 11 is arranged, the axis of which corresponds to the vertical axis plane of the Fifth wheel 1 is vertical. which is determined by the horizontal longitudinal axis and the vertical axis of the saddle bracket 1, two opposite guide arms 12 with the lateral rounded guide surfaces being provided in the rear part of the saddle bracket 1, where the axes of the guide surfaces are parallel to the vertical axis plane of the saddle bracket 1.
- the lower part of the saddle bracket 1 is formed into forked sprues, in the two parallel support rods 14 are mounted, which are adapted for attachment to the seat post and are parallel to the vertical axis plane of the saddle bracket 1.
- the saddle bracket 1 is formed by a wire skeleton 16. on the upper side of which a support body 17 is attached, to which the saddle bracket 1 is fastened by means of a mounting pad 18 with a bow screw 19, two opposite guide arms 12 with the lateral rounded guide surfaces being provided on the rear part of the support body 17.
- the axes of the guide surfaces are parallel to the vertical axis plane of the saddle bracket 1, which is determined by the horizontal longitudinal axis and the vertical axis of the saddle bracket 1, with at least one horizontal guide pin 11 being provided on the front part of the support body 17, the axis of which corresponds to the vertical axis plane of the Saddle bracket 1 is vertical.
- the saddle bracket 1, which by injection molding or by a wire skeleton 16 is formed can be performed with a different design of the front guide mechanism.
- each cube 23 is contracted with a corresponding saddle screw 26 and an inner wall of each cube 23 forms a plane with a side wall of the central groove and the second inner wall of each cube 23 forms a plane with the lateral surface of the vertical guide groove 21.
- the vertical guide groove 21 is closed in the lower part by a connecting body 27 in the form of "U", the upper end of which is screwed with the saddle screws 26 into an outer recess of the groove offset of the saddle skeleton 2, the connecting body 27 with the Outside offset sides of the groove offset is guided so that the lower open end of the vertical guide groove 21 is fastened and closed by the connecting body 27.
- At least one elastic stop 13 is provided in the front part of the saddle bracket 1.
- the elastic stop 13 is also provided on each guide arm 12 in the rear part of the saddle bracket 1.
- the elastic stops 13 are only shown on the upper side for simplification, but can also be attached on the lower sides, thus ensuring a soft support in both edge positions.
- Only one valve 31 is provided on the pneumatic spring 3 in the basic version of the pneumatically suspended saddle.
- a regulating cabinet 28 is attached in the rear part of the saddle skeleton 2, in which a regulating push button 33 is attached coaxially with the valve 31, which is guided in a guide 34 in the which is sealed by a sealing ring 35 and fastened and sealed in the outer wall of the regulating cabinet 28, a closed space having at least one channel 36 being formed within the regulating cabinet 28, where one channel 36 with an air pump 37 and another channel 36 is connected to a drain valve 38.
- the combination of the air pump 37 and the drain valve 38 can advantageously be combined with a pressure gauge 39 can be added, which is also connected to the closed space within the regulating cabinet 28 via a channel 36.
- the regulating cabinet 28 can also be fastened to the rear wall of the saddle skeleton 2 in such a way that a rear seal 29 is provided on its rear wall around the valve hole and the regulating cabinet 28 is shaped with its rear surface in such a way that it adjoins the rear part of the saddle skeleton 2 abuts and is secured against movement after the valve nut has been tightened, the valve 31 being provided with a mounting projection 32 which fits into one another in a groove in the valve hole in the rear wall of the saddle skeleton 2.
- the rear part of the saddle skeleton 2 can be arranged so that two or three individual valves 31 are provided on the pneumatic spring 3, one valve 31 serving to relieve pressure and the other valve 31 is a component of the air pump 37.
- the pressure gauge 39 can be connected directly to the pneumatic spring 3. A direct connection would likely cause life issues. It is therefore advantageous to connect the manometer 39 to the third valve 31, which is only used for pressure control in the pneumatic spring 3.
