ELECTRIC BED STRUCTURE

摘要

An electric bed includes a base and an upper body adjustment unit is pivotably connected to a top portion of the base. A head support frame is pivotably connected to the upper body adjustment unit. A front adjustment unit has a power source located at the underside of the top portion of the base. An output end of the power source is connected to a push link and a support member. The push link is connected to the underside of the head support frame to tilt the head support frame. The support member is pivotably connected to the upper body support frame which has a support face. An angle is defined between the support face and the underside of the upper body adjustment unit. The head support frame is adjusted by using the front adjustment unit and the upper body support frame is then lifted to adjust the inclination.
