Abstract: An electronic tilt sensing, tracking, and reporting system for monitoring a posture or a movement of a user seated in a chair. The system includes a mount adapted for attachment to the chair, and a sensor portion removeably secured to the mount. The sensor portion includes a sensing assembly that is adapted to sense an orientation of part of the chair relative to the ground on which the chair is supported to determine the posture or the movement of the user seated in the chair.

Abstract: A seat includes a support having a first coupling hole and a second coupling hole disposed therein. The seat also includes a seat cradle having a back, a bottom, a first side fixedly connected to the back and the bottom, and a second side fixedly connected to the back and the bottom. The seat cradle has a neutral position in which a top portion of the back is positioned forward of a bottom portion of the back, and a rear portion of the bottom is positioned below a forward position of the bottom. The seat also has a first cradle coupler extending from the first side of the seat cradle, such that the first cradle coupler cannot rotate with respect to the first side. The seat further includes a second cradle coupler extending from the second side of the seat cradle, such that the second cradle coupler cannot rotate with respect to the second side. The first cradle coupler is received in the first coupling hole and the second cradle coupler is received in the second coupling hole.

Abstract: A treatment assembly for securing a treatment member to a shaft that includes the treatment member and a female attachment member. The treatment member defines a longitudinal axis, and has a distal end and a proximal end. The proximal end includes an attachment recess defined therein. The female attachment member has a distal end, a proximal end, and a shaft recess defined in the proximal end. The female attachment member is secured in the attachment recess of the treatment member. The shaft recess is defined by an interior surface that includes a first flat surface. The interior surface includes a first detent defined therein. When the shaft is received in the shaft recess, the first flat surface is operatively engaged with a first opposing flat surface on a male attachment member and a first ball is biased into the first detent.

Abstract: A rotatable seat cradle including a lumbar supporting back, a thigh supporting front, an intermediate pelvic support bucket located between the back and the front, and an upwardly sloping transition wall that extends continuously and co-extensively between the pelvic support bucket and the thigh supporting front. The seat cradle is pivotally coupled to a stand or to a yoke connected to a chair base. The thigh supporting front of the seat cradle lies above the pelvic support bucket and cantilevers outwardly from the upwardly sloping transition wall. A seated user shifting his weight towards the front of the seat cradle pushes his legs against the thigh supporting front to generate a rotational force thereagainst for causing a corresponding rotation of the seat cradle relative to the stand or the yoke to which the seat cradle is pivotally coupled.

Abstract: An apparatus configured for exercising abdominal muscles of a user comprises an elongated support structure, a translatable member, a foot support assembly and a foot support lifting mechanism. The elongated support structure has a first end and a second end and the translatable member has a first end and a second end. The translatable member is slidably attached to the elongated support structure for enabling translation of the translatable member with respect to the elongated support structure. The foot support assembly is movably mounted on the elongated support structure. The foot support lifting mechanism is coupled between the first end of the translatable member and the foot support assembly whereby translation of the translatable member toward the second end of the elongated support structure results in a corresponding upward movement of a foot engaging portion of the foot support assembly.
