Title:
寝姿勢制御ベッドシステム
Document Type and Number:
Japanese Patent JP6450431
Kind Code:
B2
Abstract:
The sleeping-posture-control bed system includes a bed floor including a back-lifting portion for lifting the user's back, a bed-floor support body supporting the bed floor, and a back-lifting driver for lifting the head side of the back-lifting portion. The back-lifting portion includes a back-receiving surface and a head-receiving surface tiltable at different angles. The back-lifting driver lifts the back-receiving surface and the head-receiving surface, satisfying Mathematical Formula (1): 0°<θx≰70°, −45°≰θy<0°, and −30°≰θx+θy (1) where θx is the tilt angle of the back-receiving surface when tilted, and the tilt angle of the back-receiving surface when the back-receiving surface is not lifted is set to be 0°; and θy is the tilt angle of the head-receiving surface when the angle of an extended line of the back-receiving surface at the tilt angle θx is referred to as 0°.
