Definitions

  • the invention relates to a device for simulating acceleration forces acting on the human head and to a method for simulating such acceleration forces.
  • Acceleration forces - also referred to as g-forces - are called loads acting on the human body (or other object) due to a change in magnitude and / or direction of velocity.
  • the acting on the head acceleration force is thus the force that acts against the direction of acceleration of the head due to the inertia of the head.
  • High acceleration forces or g-forces occur, for example, when traveling on a rollercoaster. Further, even in an acceleration operation, a braking operation or a cornering with a vehicle, acceleration forces or g-forces which act on the human body and which can be very large depending on the rate of change of the acceleration occur. For example, racing drivers such as Fl racers are exposed to very large g-forces.
  • the g-forces acting on the human body or on the head simulate to give the player an even more realistic driving experience. Further, it is desirable to provide a realistic simulation of body-to-head acceleration forces for "real" racing simulators, where professional racers as well as non-racers can simulate a race on a particular circuit.
  • FIG. 1 Such a device known from the prior art is shown in FIG.
  • This device essentially consists of a helmet 10 on which at least one, preferably at least four tension elements or hydraulic elements 1 1 are arranged.
  • the tension elements or hydraulic elements 11 are connected on the one hand with the helmet 10 and on the other hand with a stationary frame.
  • the tension elements or hydraulic elements 11 By means of the tension elements or hydraulic elements 11, the helmet 10 and thus the head can be moved two-dimensionally in any direction, whereby the action of an acceleration force on the head is to be simulated.
  • this known from the prior art device has the disadvantage that it has relatively large dimensions, for example, a width and a depth of about 150 cm. For domestic use, therefore, this device is not practical and is therefore used almost exclusively by professional racers for training purposes.
  • Object of the present invention is therefore to provide a device for simulating acceleration forces acting on the human body or on the human head, which at least partially avoids the disadvantages known from the prior art and on the one hand is space-saving, too be used in home use, and on the other hand, the natural freedom of movement of the head and the field of view is not limited and can also be used for training the neck and neck muscles if necessary.

  • "Normal position" means that the head or base unit is oriented forward relative to the human body and the angle of rotation of the head or base unit relative to this normal position is 0 °. If the head and thus the base unit rotated to the left or to the right, ie, rotated about the vertical axis HA (see Fig. 2), the rotation angle of the head or the base unit relative to this normal position changes, ie, the rotation angle is greater or less 0 °.
  • the displacement of the body relative to the base unit results in a weight shift of the body relative to the base unit, which causes the wearer of the base unit to feel a head-acting acceleration force, depending on which direction the body is displaced. If, for example, the body is displaced towards the front of the base unit, a negative acceleration is simulated which arises, for example, during a braking process in a vehicle. As a result, a forward g-force acts on the head which pushes the head forward or moves forward.
