Abstract: A back adjustable electrical bed frame comprises a head panel, a back panel, a buttocks panel, a thigh panel, a shank panel, a back pusher motor and a leg pusher motor. The leg pusher motor drives the buttocks panel through a scissor support assembly. The shank panel, parallel to the base, moves back and forth. The back panel has a back panel pivot at a quarter to a half of its lower part. The back panel is fixed to the base by a column having one end fixed to the base and the other end connected to the back panel pivot. The back pusher motor has a front end pivot connected with the back panel and a rear end pivot fixedly connected with the base. The front end pivot, the rear end pivot and the back panel pivot form a triangle to position an angle of the back panel.
