摘要:
An apparatus for sitting, including: a keystone assembly which connects various parts of the apparatus; a back that provides support for at least a person's back or shoulders; a floating lumbar support, which provides support for a person's lower back, attached to the keystone assembly; a seat that can adjust between a forward tilted and reclined position; a plurality of rollers, disposed on the keystone assembly, on which the seat rests; a central column, attached to the keystone assembly, on which the seat can spin; and a lower torsion spring connected to the seat and disposed on the keystone assembly allowing controlled movement of the seat.
摘要:
A mechanical device, comprising a single plate that is connectable under a chair and with which an actuation rod can be associated transversely for the combined rotation and translational motion of an intermediate element pivoted inside a box-like body that is partially accommodated at a first seat formed below the single plate, the box-like body being associable with a central column and interacting with oscillation compensators that interact with the single plate.

A reclining apparatus is provided between a post and a seat of a chair. The reclining apparatus includes a first joint for attachment to the post, a second joint pivotally connected with the first joint for supporting the seat and a locking device for locking the second joint in one of several reclined positions relative to the casing.

A chair has a seat (4) and a backrest (5) which are independently pivotable within limits at extremities. The seat is biassed upwardly at the front and the backrest is biassed forwardly. The seat and the backrest have a common pivot joint (8), under the center of gravity of the occupant. There are no occupant-operated controls as the chair responds automatically to the posture of the occupant, providing full support at all relative positions of the seat and the backrest in a balanced manner for occupants of a wide range of weights.

A seat platform carrier for a chair tilts backward and forward relative to a base part when a load, such as a person sitting is the chair, is placed on the seat carrier. A resetting mechanism positioned the seat platform carrier to the same initial position when the load is removed. A lamellar pack attached to a hand lever provides the user with a means to lock the seat platform carrier in a desired tilted position. A height adjusting actuator is included in the base part to permit the user to select an appropriate seat platform height. A user sitting on the seat platform carrier is able to freely tilt forward or backwards.

A seat part (20) of a functional chair is connected to a head part (16) of the pedestal (10) via a joint (18) comprising elastomeric material (38) such that it can be tilted relative to the head part (16) against spring force. A backrest part (28) is similarly connected via a joint (26) to a backrest support (24) which allows the backrest part (28) to tilt relative to the backrest support (24) about a horizontal axis and about an axis which is parallel to the longitudinal direction of the backrest.
摘要:
A support stand, support stand assembly, and method of making the same with the support stand featuring a base with central hub-like reception area either capped or uncapped at its bottom and a supporting rod that has a diameter less than that of the side wall defining the reception area so as to form an annular gap. An elastomer material, which is preferably a liquid urethane that cures at room temperature, is poured into the gap so as to form an energy management member which acts as a flexible cushioning element by helping to dampen and diffuse rocking forces of the supporting rod with respect to the base. The energy management member also acts to glue the supporting rod to the base through the bonding properties.
摘要:
For automatically adjusting the tilting resistance of a chair seat (6), which is tiltably attached on a base column (1) via a horizontal shaft provided across the chair, and where tilting resistance and springing are determined by two spring elements (13, 14), one spring is compressed by tilting in one direction and the other spring compressed by tilting in the opposite direction. The spring force is adjustable. In order to be able to adapt the tilting resistance to the seat's/backrest's setting automatically, the spring elements (13, 14) are connected to the seat/backrest by mans of a connecting element which directly influences their spring force by an adjustment of the seat and/or backrest.
摘要:
A chair with a moveable seat panel mounted springingly on a support and a back-rest has a seat panel made from pliant panel material which is guided down around the front edge of the seat panel in a U-shape and then rigidly sandwiched in the support. A guide bar which is pivotably mounted on the support is directed backwards and is rigidly connected with the underside of the rear end portion of the seat panel.

A seat assembly for a vehicle which includes a seat, a seat back, and mounting means mounting the seat for movement in fore and aft directions in the vehicle along an upwardly concaved arcuate path. The arcuate path has a radius of curvature which is sufficiently large to timely move in front of and to contain the person's buttocks, to significantly slow the rate of deceleration of the person seated on said seat, and being sufficiently small to convert a portion of the linear momentum of the person's buttocks to angular momentum thus maintaining frictional contact of the person's buttocks with the seat during stopping at a high rate of deceleration. A seat assembly which includes a lower lumbar support member that is coupled from movement in response to pelvic tilting movement of the seat also is shown. The method includes the step of employing a seat mounted for movement along an upwardly concaved, arcuate path in the fore-aft direction in a vehicle to effect reduction of injury of a person seated on the seat during a frontal collision of the vehicle with an object.
