Problems solved by technology

The disadvantage of such a solution is that the thread of the screw must have self-locking, whereby the settings adopted during use are not changed unintentionally
However, self-locking is accompanied by significant friction, whereby in practice a large manual force is applied to the setting process
However, said manual force is hardly compatible with today's comfort requirements

Embodiment Construction

[0022] figure 1 An exemplary embodiment of the vibrating system according to the invention is shown viewed obliquely. The vibratory system consists of a conventional cross tie system (Scherenlenker system) with a lower frame 1 and an upper frame 2, which are connected to each other via two cross members, an outer cross member 3 and an inner cross member 4 to enable them to vary their vertical spacing from each other. For this purpose, the two cross members 3 , 4 are connected to each other in such a way that they can revolve around a horizontally extending axis of rotation 5 (see Image 6 ) to rotate. At the same time, one of its two ends is connected to one of the two frames 1 , 2 each about a fixed axis and is made movable relative to the other frame 2 , 1 by its corresponding other end. support. Since such systems are known in the prior art to those skilled in the art, they will not be described in detail below.

Abstract

The invention relates to a vibration system for a vehicle seat, and the system comprises two frames, wherein the frames are connected through two connected cross parts which can rotate around the rotation axis, and the vertical distance between the corss parts can be changed; a main spring is arranged between one frame and one cross part, the main spring is hinged to the cross part through the first end and is hinged to a lever through the second end and the first hinged point, and the lever is connected with a frame through the rotation axis; according to the lever, a first lever arm is arranged between a first hinged point of a first force direction main spring of the main spring on the lever and the rotation axis of the lever, and the first lever arm under the small stress of the main spring is greater than the same under the high stress of the main spring; an energy storage is arranged between the lever and a frame, the energy content of the engergy storage relates to the main spring stress, and the energy content under the high stress of the main spring is less than the energy content under the low stress of the main spring.

Description

technical field [0001] The invention relates to a vibrating system for a vehicle seat, having two frames, a lower frame and an upper frame, which are connected to each other via two cross members rotatably about an axis of rotation, an inner cross member and an The outer cross members are connected to each other in such a way that the frames are variable in their vertical spacing from each other, wherein a main spring is arranged between one of the two frames and one of the two cross members. Background technique [0002] In order to isolate the driver of a commercial vehicle from the vibrations that occur while the vehicle is in motion, vibration systems are used for vehicle seats. These vibration systems serve, on the one hand, to increase comfort and, on the other hand, to assist the driver to maintain a state of alertness, awareness and fitness for driving a motor vehicle for a longer period of time. The two main vibration systems used either use mechanical springs or a...
