Abstract
A seating arrangement may include a backrest with a shroud and/or anchor elements securing a membrane and flexible material. An actuator may operate may simultaneously operate boost/stop components acting on a tilt control mechanism of the seating arrangement. An armrest assembly may include a strap, tubular member and adapter interfacing between the strap and tubular member.
Claims18
A seating arrangement comprising:
- a base;
- a seat moveably coupled to the base, wherein the seat is moveable between an upright seat position and a reclined seat position;
- a backrest moveably coupled to the base, wherein the backrest is moveable between an upright backrest position and a reclined backrest position;
- a spring engaged with at least one of the seat or backrest;
- a spring actuator rotatable between:
- (i) a first disengaged position wherein the actuator is disengaged from the spring;
- (ii) an engaged position wherein the actuator engages the spring such that the spring applies a biasing force to the at least one of the seat or backrest as the seat and backrest are moved to the reclined seat and backrest positions respectively;
- and
- (iii) a second disengaged position wherein the actuator is disengaged from the spring, wherein the first and second disengaged positions are different;
- and
- a stop member moveably coupled to the actuator, wherein the stop member is translatory between:
- (i) an engaged position when the actuator is in the first disengaged position, wherein the stop member engages and prevents at least one of the seat and backrest from moving to the reclined seat and backrest positions respectively when the stop member is moved translatory to the engaged position of the stop member;
- (ii) a first disengaged position when the actuator is in the engaged position of the actuator, wherein the stop member is disengaged from the at least one of the seat and backrest such that the at least one of the seat and backrest may be moved to the reclined seat and backrest positions respectively when the stop member is moved translatory to the first disengaged position of the stop member;
- and
- (iii) a second disengaged position when the actuator is in the second disengaged position of the actuator, wherein the stop member is disengaged from the at least one of the seat and backrest such that the at least one of the seat and backrest may be moved to the reclined seat and backrest positions respectively when the stop member is moved translatory to the second disengaged position of the stop member, wherein the first and second disengaged positions of the stop member are different.

A seating arrangement comprising:
- a base;
- a seat moveably coupled to the base, wherein the seat is moveable between an upright seat position and a reclined seat position;
- a backrest moveably coupled to the base, wherein the backrest is moveable between an upright backrest position and a reclined backrest position;
- a spring engaged with at least one of the seat or backrest;
- an actuator comprising a pinion gear rotatably coupled to the base about a rotation axis and an arm extend radially from the pinion gear, wherein the pinion gear is rotatable in opposite first and second rotation directions, and wherein the arm engages the spring as the pinion gear is rotated to a predetermined biasing position;
- and
- a stop comprising a linear rack moveably engaged with the pinion gear, wherein the linear rack is translatory in opposite first and second translatory directions in response to the rotation of the pinion gear in the opposite first and second rotation directions, and wherein the linear rack comprises a stop surface engaging one of the seat or backrest when the linear rack is moved translatory to a predetermined stop position.

A method of adjusting a seating arrangement comprising:
- moving a seat coupled to a base between an upright seat position and a reclined seat position;
- moving a backrest coupled to the base between an upright backrest position and a reclined backrest position engaging at least one of the seat or backrest with a spring;
- rotating a spring actuator between:
- (iv) a first disengaged position wherein the actuator is disengaged from the spring;
- (v) an engaged position wherein the actuator engages the spring such that the spring applies a biasing force to the at least one of the seat or backrest as the seat and backrest are moved to the reclined seat and backrest positions respectively;
- and
- (vi) a second disengaged position wherein the actuator is disengaged from the spring, wherein the first and second disengaged positions of the actuator are different;
- and
- translating a stop member coupled to the actuator between:
- (iv) an engaged position when the actuator is in the first disengaged position, wherein the stop member engages and prevents at least one of the seat and backrest from moving to the reclined seat and backrest positions respectively when the stop member is moved translatory to the engaged position of the stop member;
- (v) a first disengaged position when the actuator is in the engaged position of the actuator, wherein the stop member is disengaged from the at least one of the seat and backrest such that the at least one of the seat and backrest may be moved to the reclined seat and backrest positions respectively when the stop member is moved translatory to the first disengaged position of the stop member;
- and
- (vi) a second disengaged position when the actuator is in the second disengaged position of the actuator, wherein the stop member is disengaged from the at least one of the seat and backrest such that the at least one of the seat and backrest may be moved to the reclined seat and backrest positions respectively when the stop member is moved translatory to the second disengaged position of the stop member, wherein the first and second disengaged positions of the stop member are different.
