Abstract
A therapeutic back support device including a back support portion that automatically and repeatedly moves forward to maintain engagement with a user's back as the user moves forward with respect to a chair seat. The back support portion substantially resists backward motion and provides substantially continuous therapeutic support to the user's spine pending a release signal.
Claims20
A chair comprising:
- a seat portion;
- and
- a back portion, said back portion including a mechanism, said mechanism being adapted to automatically and repeatedly move said back portion forward in respective forward motions with respect to said seat portion so as to follow a motion of a user's back and being adapted to automatically and repeatedly substantially prevent backwards motion of said back portion between said repeated forward motions.
A chair comprising:
- a seat portion;
- and
- a back portion, said back portion being adapted to automatically and repeatedly move forward with respect to said seat portion so as to follow a motion of a user's back and being adapted to automatically and repeatedly arrest substantial backwards motion of said user's back between said repeated forward motions.
A seating controller comprising:
- a seat supporting member;
- a back supporting member;
- an interface device, said interface device being mutually coupled to said seat supporting member and said back supporting member, said interface device being adapted to automatically move said back supporting member in a first direction, said interface device being adapted to automatically substantially prevent said back supporting member from moving in a second direction opposite said first direction until said interface device receives a release signal, whereby a seat back portion coupled to said back supporting member is adapted to move forward automatically and repeatedly to contact a user's back and, after each of said repeated forward motions, automatically resist rearward motion unless said release signal is received.
