Abstract:
1. A method of controlling lifting of bottom sections of lying furniture having a back bottom section for lifting a back bottom section for lifting a back section of a lying person and a knee bottom section for lifting his/her knee section, and in which the respective bottom sections can be operated selectively either independently or in an interlocked manner by lifting mechanisms actuated by a control means, comprising the steps of first either (a) or (b) as follows: (a) sending an interlocked operation command from an interlocked operation switch to an operation control means to operate the bottom sections in an interlocked manner, subject to a condition that commands are not issued from plural independent operation switches, or (b) sending an operation command to a control means to actuate the lifting mechanisms; and then step (c) as follows: (c) sending an interlocked operation command from an interlocked operation switch to an operation control means when all of the bottom sections are initially lying flat, to first begin to pivotally rotate and lift the back bottom section, and, at a predetermined time thereafter, to initiate lifting of the knee bottom section.
