Definitions
- Motorized adjustable support device for upholstering a seating and / or reclining furniture
- the invention relates to a motor-adjustable support device of the type mentioned in the preamble of claim 1 for upholstery of seating and / or reclining furniture.
- Such support devices are generally known in the form of motorized slatted frames for beds or the like.
- a motor-adjustable support device of the type in question is known in the form of a slatted frame, which has a base body with a frame to which a plurality of support parts which are adjustable relative to one another are connected.
- the known support device has a drive unit detachably connected to the base body, which has a housing.
- the housing has two spaced-apart recesses into which a shaft rotatably mounted on the base body of the support device engages in the assembly position of the drive unit, which shaft is in operative connection with a support part to be adjusted and can be rotated by means of the drive unit.
- the drive unit is arranged below the frame of the slatted frame.
