Definitions

  • the present invention relates to a motorcycle seat according to the preamble of claim 1.
  • motorcycle seats usually consist of a seat support element, a homogeneous foam core applied to it and a seat cover stretched over the foam core.
  • the foam core is intended to distribute the body weight of the driver over the largest possible “effective seat” in order to keep the surface pressures within limits and thus to achieve a comfortable seat. because the motorcyclist's legs remain on the footrests even when braking or shifting and are not or only slightly moved. Compared to car seats, motorcycle seats have significantly higher surface pressures. This can lead to a deficiency supply of the body tissue in the heavily loaded "buttocks areas".
  • the object of the invention is to provide a motorcycle seat in which a deformable cushion-like element or several such cushion-like elements are integrated, the motorcycle seat offering greater seating comfort.
  • the invention is based on a motorcycle seat with a foam core and a seat cover, wherein at least one, but preferably a plurality of deformable cushion-like elements are arranged in the foam core.
  • “In the foam core” means that the cushion-like element is arranged wholly or partly in the foam core.
  • the at least one cushion-like element is gas-tight and can be inflated or evacuated via a fluid connection. About the filling or pressure state inside the cushion-like element The seating comfort properties of the motorcycle seat can be changed.
  • the essence of the invention is that an elastic material is arranged in the at least one cushion-like element.
  • the stretch-elastic material can have the shape of a block, a cuboid, a prism or another three-dimensional shape, for example. It is also conceivable that the pillow-like element is filled with a granulate or with balls made of an elastic material.
  • the above-mentioned water bed or air mattress effect can be almost completely avoided by one or more such "foam-filled airtight cushions", which are integrated in the motorcycle seat.
  • the stretch-elastic material which is arranged in the cushion-like element (s), for example, can The same material can be used as for the foam core of the motorcycle seat.
  • the force-displacement characteristic or the pressure-displacement characteristic of the cushion-like elements depends in particular on the air or gas pressure in the cushion-like element the elastic or compressive elasticity of the elastic material and the elasticity of the cushion-like element itself.
  • the pressure-displacement characteristic and thus the seating comfort can be changed.
  • the pressure state in the pillow-like elements can be controlled via an "air pump” either “manually” by operating a switch or automatically by a program which pressurizes or evacuates the pillow-like elements. To increase the hardness of the seat, excess pressure can be generated in the cushion-like elements. To "adjust" a soft seat the pillow-like elements are vented or a "negative pressure" can be set in the pillow-like elements.
  • Two such cushion-like elements are preferably integrated in the foam core of the motorcycle seat.
  • one pillow-like element is arranged in the area under the “right ischial hump” and the other pillow-like element in the area under the “left ischial hump” of the motorcyclist or passenger.
  • the pressure in the cushions can be varied at the same time, which changes the load between the buttocks and the rest of the seat.
  • the pressure states in the pillow-like elements can also be varied alternately.
  • One pillow-like element can thus be alternately inflated and the other pillow-like element can be vented or evacuated.
  • the pressure can be set or changed “manually” by actuating a switch.
  • the pressure state in the cushion-like elements can also be changed by an automatic program with a predetermined cycle time of, for example, 30 seconds
  • the seat and buttocks areas are alternately loaded and relieved, which favors the nutrient supply to the buttocks tissue.
  • the pressure variation is preferably such that only soft parts of the motorcycle rider are moved, but not the skeleton.
  • the individual cushion-like elements can be inflated or evacuated independently of one another.
  • they can also be coupled to one another via a fluid connection, so that there is always the same or approximately the same pressure in the pillow-like elements.
  • Figure 1 is a schematic representation of a motorcycle seat with two cushion-like elements and a pressure supply unit integrated in the motorcycle seat;
  • Figure 2 shows a cross section through the motorcycle seat of Figure 1 in the area of the pillow-like elements
  • Figures 3, 4 is a perspective view and a cross section of one of the pillow-like elements
  • Figure 5 is a circuit diagram of a circuit arrangement for controlling the pillow-like elements.
  • Figure 1 shows a motorcycle seat 1 with a seat portion 1a and a lumbar portion 1b, which is pulled up and which supports the buttocks of the motorcycle rider from behind when accelerating.
  • An airtight, inflatable, cushion-like element 2, 3 is arranged in the seat section 1 a in the area of the left and right seat bones.
  • the two pillow-like elements are each connected to a pressure supply unit 4 formed by a pump, valves and an electric motor via fluid lines, not shown here.
  • the pressure supply unit 4 is also integrated into the motorcycle seat, specifically in the transition region between the seat section 1a and the lumbar section b.
  • Figure 2 shows a cross section through the motorcycle seat 1 of Figure 1 along the section plane, which is designated in Figure 1 with the reference number 5. The cross section shown in FIG.
  • the foam core 7 is covered with a seat cover 8.
  • the foam core 7 In the area of the left and right ischial tubercles, the foam core 7 each has a recess 9, 10.
  • An airtight cushion-like element 11 or 12 is arranged in each of the recesses 9, 10.
  • each of the two airtight cushion-like elements 11, 12 is filled with a foam block 13, 14 which is prismatic in cross section, or a foam block 13 or 14 is arranged in each of the cushion-like elements 11, 12.
  • the foam blocks 13, 14 can consist of the same material as the foam core 7. Alternatively, the foam blocks can also be cuboid.
  • FIGs 3, 4 show the pillow-like element 11 in perspective or in cross section.
  • the pillow-like elements 11, 12 are constructed identically.
  • the plastic film from which the pillow-like elements are made can additionally be stretch-elastic. However, it does not necessarily have to be stretch-elastic.
  • the cushion-like element 11 is made from an upper plastic film 15 and a lower plastic film 16, which are welded to one another airtight in regions 17, 18.
  • the foam block 13 which is arranged in the pillow-like element, is somewhat smaller than the pillow-like element 11, so that air can be pumped into the interior of the pillow-like element 11 via a fluid connection 19 which is welded between the upper film 15 and the lower film 16.
  • the interior of the pillow-like element 11 can be vented via the fluid connection 19 or a negative pressure can be generated in the interior of the pillow-like element 11.
  • FIG. 5 shows a circuit diagram of a pressure supply device 19, via which the pressure states in the cushion-like elements 11, 12 can be controlled or regulated.
  • the pressure supply device 19 can also be integrated in the foam core of the motorcycle seat 1.
  • the pressure supply device 19 has an electric motor 21 which is controlled by control electronics 20 and which drives a pneumatic pump 22.
  • a pneumatic output 23 of the pneumatic pump 22 is connected to inputs 24, 25 of solenoid valves 26, 27.
  • the cushion-like element 11 is connected to an output of the solenoid valve 26.
  • the cushion-like element 12 is connected to an output of the solenoid valve 27.
  • the solenoid valves 26, 27 also each have a vent 28 and 29, respectively.
  • the solenoid valves 26, 27 are electrically controlled by the control electronics 20.
  • the control electronics 20 can in turn be "manually" controlled by the motorcycle driver via an operating switch 30.
  • the operating switch 30 can be arranged on the handlebar, for example. Alternatively, the operating switch can also be arranged on the seat in
  • the pressure in the cushion-like elements 11, 12 can be changed individually or simultaneously manually via the control switch 30 or the control switch device 30. Furthermore, it can be provided that the Control electronics 20 implemented automatic program, the pressure states in the pillow-like elements 11, 12 are automatically changed cyclically.
