Technical part

The present invention is in the field of alternative seats, especially bicycle seats.

State of the art

Conventional bicycle seats are designed so that most of the occupant's body weight is concentrated on the relatively small buttock area. The other part of the body weight is intercepted by the hands on the handlebar grips. The resulting when driving over bumps, sometimes significantly increased pressure, directly affects as a blow to the spine and often not sufficiently strong muscles. Numerous suspension systems with different levels of shock absorption success have usually been installed in different parts of the vehicle, but without solving the causative problem - the blow goes over the buttocks in the lumbar region. In the classic bicycle positions, especially in sports bikes, an extreme curvature of the lumbar region is required to drive stable between the pedal, seat and handlebars.

Bicycles with alternative seating positions, such as recumbents, already try to avoid the high load on the lower back. However, a normal bicycle can not be easily converted to a recumbent bike with the help of a new bicycle seat. In order to occupy a suitable reclining position, an investment of a complete new purchase is required, which is significantly higher than that of a normal bicycle. In addition, a recumbent is a change of driving style, which differs significantly from that of a normal bike. The recumbent bicycles with their compared to normal bicycles a much lower height, which makes it more difficult, especially in road traffic, to be perceived by other road users. The wider axle of the three- or four-wheeled recumbents also requires more space on the tracks, which also limits the driving possibilities compared to normal bicycles.

Long journeys with conventional bicycles burden the hands and wrists, which can often cause pain or fatigue. The permanent weight of the bent forward body and the road-related strokes on the front wheel in the hands and wrists can here lead by numbing the blood vessels in the hand to numbness and tingling, which can severely negatively affect the driving pleasure. Relief in such cases can only enable one-armed single-handed driving or freehand driving by sitting up. With one-handed driving, the pressure on the one supporting hand then increases at times, which in the medium to long term can also increase the negative effect. In hands-free driving, however, the performance of pedaling is no longer optimal. In addition, the weight increases on the back, since now the entire weight is held by the buttocks.

Description of the invention

The invention disclosed here solves the known problems with a completely new reclining seat system ( 1 ) with at the same time almost unchanged seating position. The main innovation is the shifting of body weight from the buttocks and hands to the upper body. The weight of the upper body is enhanced by an ergonomically shaped, padded and sprung upper body support ( 2 ) received by the bicycle and by a likewise ergonomically shaped, padded and sprung buttocks support ( 3 ) limited. To relieve the lower back maximum, the upper body support ( 2 ) only from the hip area. As a result, the pelvis, and also the crotch area, are exposed and are gently slid by the buttock part from slipping off the upper body support (FIG. 2 ) braked.

The inclination angle clearance of the cushioning upper body support ( 2 ) can be adjusted via an adjustment device ( 7 ) are set to the desired driving position. In addition, the spring strength on the weight of the driver with a spring rate control ( 8th ) so that the suspension optimally absorbs at the preset inclination angle. For each driver, there will be an optimal angle of inclination, which brings the desired relief for the spine and hands in the desired driving position. A suitable adjustment of the reclining seat system ( 1 ) is therefore required.

The reclining seat system ( 1 ) is designed to fit on any standard bicycle can be mounted with exchangeable bicycle saddle. A main support tube ( 11 ) of the reclining seat system ( 1 ) provides the support and is the only necessary connection to the bicycle frame ( 12 ). The feather ( 9 ), the inclination angle adjustment device ( 7 ) and the spring rate control ( 8th ) are in the roundish center support tube ( 4 ) between upper body support ( 2 ) and buttocks support ( 3 ) integrated.

The sitting or reclining position must not be higher than that of a normal bicycle saddle because of the need to have a safe standing position even when stationary.

In order to facilitate the ascent to the bicycle, the upper, movable support system ( 13 ) over the round central support tube ( 4 ) are tilted backwards so that the buttocks support ( 3 ) is significantly lower than in the later driving position. A slight forward tilt in the driving position leaves the reclining seat system ( 1 ) engage in the preset inclination angle clearance, so that accidental back-tilting is prevented.

The detent lock for releasing the tiltable support system ( 13 ) can with a smooth, under the upper body support ( 2 ) mounted spring tension locking lever ( 15 ) can be solved again with one hand, so that an easier descent in the lower seating position is possible.

A tilt function for a lower ascent height is not mandatory if the buttocks support ( 3 ) does not protrude beyond the normal saddle height. As a result, a normal ascent by placing one foot on the front pedal and then stretched behind the bike along the seat curved leg is still possible.

The shape and size, in particular the upper body support ( 2 ) should be offered in various design variants, for example, to provide optimized for children, men or ladies ergonomics and efficiency. Also for athletes weight and streamline optimized shapes and materials are useful and possible. In the context of certain margins, at least size-adjustable adjustment options can be easily integrated in order to make the correct support positions adaptable to different body sizes. For example, the displacement of the support supports (upper body ( 2 ) and buttocks support ( 3 )) on the column supports ( 23 ) by sliding rails ( 5 ) and locking screws ( 17 ) possible.

For longer trips, the underside of the upper body support ( 2 ) serve as a carrier for travel provisions, such as beverage bottles or for other travel items, such as repair kit, by different bags ( 19 ) or bottle holders ( 20 ) to be assembled.

Description of preferred embodiments

The preferred embodiment of the reclining seat system ( 1 ) is a universally applicable upgrade system, which in exchange with the bicycle saddle on the main support tube ( 11 ) in the seat post holder ( 24 ) of the bicycle frame is inserted and fixed.

The padded upper body storage area ( 25 ) is large enough to hold the upper body from the hip bone to the upper chest. In width, the upper body storage area ( 25 ) also the abdominal and chest area. The two sides of the shelf have a right and left side separate padding. The cross-section of the upper body tray ( 25 ) has a slight curvature downwards, so that the upper body can take a stable and at the same time comfortable position. The basic form of the upper body storage area ( 25 ) roughly corresponds to the shape of a beech leaf. The respective "corners" (top and bottom left and right respectively) are slightly recessed so as not to crush or restrict the movement of the shoulders and thighs during use.

The buttocks support ( 3 ) is in the preferred embodiment, also two-piece padded and does not protrude beyond the starting point of the upper body support ( 2 ) upwards. The buttocks support ( 3 ) is slightly wider, but lower than normal bicycle saddles, as the contact points touch the buttocks slightly higher up.

Both supports ( 2 + 3 ) are on the bottom via a sliding rail ( 5 ) on the respective support beam ( 6 ) held. The support beams ( 6 ) are provided via a semicircular center support tube ( 4 ) in such a way that the two supports ( 2 + 3 ) are at an angle of 80 ° to 100 ° to each other. Between the two supports ( 2 + 3 ) is a sufficiently large clearance, so that the crotch area not on the upper body tray ( 25 ) is pressed, even if it is padded. This gap can vary depending on gender and body size, so that a ladies' and men's variant can be distinguished. The center support tube ( 4 ) is up with a foam rubber ( 16 ) sufficiently padded to prevent accidental slippage of the driver on the center support tube ( 4 ) to produce no injuries.

In the preferred embodiment, the semicircular center support carrier tube ( 4 ) via a strong hinge ( 18 ) with the main carrier tube ( 11 ) connected in such a way that a tilting movement before and back is enabled. One on the hinge ( 18 ) fixed spring mechanism ( 9 ) springs the center support tube ( 4 ) so strong that it can compensate for the weight of the driver and the shocks when driving on uneven ground under full load. The spring mechanism ( 9 ) can with respect to the strength with an Allen screw ( 27 ) at the top of the spring housing ( 28 ) are adjusted so that different loads and weights lead to optimal cushioning for the driver.

Also, the driver's preferred angle of inclination is by means of an adjustment device via the spring mechanism with an Allen screw ( 29 ) at the end of the spring housing ( 28 ) adjustable. The maximum lowest and highest inclination point of the upper body support ( 2 ) can be preset as driver-individual. The upper body support ( 2 ) is sprung in the lowest inclination angle even with very strong blows, so that a hard penetration is prevented. A lock for the maximum highest inclination angle thus prevents unwanted, uncontrolled rocking back of the upper body support ( 2 ).

The material used is a lightweight steel alloy for the load-bearing parts, which produces the required stability and elasticity according to the maximum permitted body weight per size variant. The support base plates ( 10 ) are in a sturdy but lightweight plastic design and are padded with a 1.5 cm thick foam rubber coated with a waterproof upper.

Optional accessories

The lower surfaces of the upper body support ( 2 ) come with two pockets ( 19 ) or bottle holders ( 20 ) - one on the left and one on the right - so you can store drinks bottles or other travel items here. The bags ( 19 ) are closable so that they are not open in the empty or filled state and form no unnecessary additional air resistance. This is with a self-closing rubber pocket edge ( 30 ) or by Umklapplasche with Velcro or button closure.

An in the reclining seat system ( 1 ) built-in anti-theft protection provides additional protection for the helmet. The helmet can be placed in the parked condition of the bicycle under the upper body support ( 2 ) using the lying-in-the-seat system ( 1 ) integrated safety rope ( 21 ) are secured in such a way that it and the entire recumbent seat system ( 1 ) can not be stolen. The integrated and with the reclining seat system ( 1 ) permanently connected safety rope ( 21 ) is performed by the helmet and by a self-contained frame opening and in the lock receptacle ( 31 ). By opening the lock ( 32 ) the safety rope ( 21 ) released again. By a maximum forward tilted upper body support ( 2 ) can also protect the helmet from wet weather.

The reclining seat system ( 1 ) also has a rain cover. One behind the buttocks support ( 3 ) integrated bag ( 26 ) contains a rain cape, which is fixed to the buttocks support ( 3 ) in the bag ( 26 ) connected is. The rain cape is in the bag ( 26 ) in such a way that it is completely in the bag ( 26 ) is recorded. To use the rain cape, the bag ( 26 ) and roll out the raincover cape until it is completely unrolled. The rain cape is made precisely and covers the maximum adjustable size of the reclining seat system ( 1 ). In addition, it has a peripheral, sewn-in elastic band, which provides a secure hold for the rain cape over the entire reclining seat system ( 1 ). After using the rain cap it is rolled up again and in the bag ( 26 ) stowed away again.
