Automatic tilting of a support surface on a support device

Abstract

The invention relates to a movement device for mounting in a support device and a support device which entails that at least one part of the device actively moves in a continuous, predetermined fashion. The pattern of the movement occurs independently of the movement of the user. The movements entail that the muscles of the user are continuously activated changing the muscle strain of the user, which entails that the user does not get tired and sore as quickly as usually. The invention further relates to a support device, such as a bed or a chair comprising such a movement device.

1 . A movement device for mounting in a support device for supporting a user, such as a support device comprising at least one support surface, said movement device comprises actuating means for tilting said at least one support surface of said support device, said tilting of said at least one support surface occurs without impact from the user. 
     
     
         2 . A movement device according to  claim 1 , where said movement device comprises actuating means for tilting two support surfaces of said support device, said tilting of said two support surfaces being a cyclic movement, the cycle time of said two support surfaces being different from each other. 
     
     
         3 . A movement device according to  claim 2 , where the cycle time of the one support surface is twice the cycle time of the second support surface. 
     
     
         4 . A movement device according to  claims 1 - 3 , where said movement device comprises actuating means for tilting the lumbar back part of said support device. 
     
     
         5 . A movement device according to  claims 1 - 4 , where said movement device comprises actuating means for tilting the seat part of said support device, said tilting being a sideways tilting. 
     
     
         6 . A support device for supporting a user, such as a sitting device or a lying device comprising at least one support surface, wherein said at least one support surface is tilting, said tilting of said at least one support surface occurs without impact from the user. 
     
     
         7 . A support device according to  claim 6  comprising two support surfaces, wherein said two support surfaces are tilting, said tilting of said two support surfaces occurs without impact from the user. 
     
     
         8 . A support device according to  claim 7  comprising two support surfaces, wherein said two support surfaces are tilting, said tilting of said two support surfaces being a cyclic movement, the cycle time of said two support surfaces being different from each other, 
     
     
         9 . A support device according to  claim 8  where the cycle time of the one support surface is twice the cycle time of the second support surface. 
     
     
         10 . A support device according to  claims 6 - 9  where said support device can identify the user by person identification and thereby adjust according to the identified user.
