Lindberg, Grand Rapids, Micln, assignors to American Seating Company, Grand Rap- I ids, Mich.,-a corporation of New Jersey Application August 11, 1947, Serial No. 767,992
3 Claims.
The present invention relates to chairs and more particularly to chairs of the retracting type for use in theaters, auditoriums and the like. Some of the subject-matter herein disclosed is claimed in our co-pending application Serial No. 784,182 filed November 5, 1947, which matured into Patent No. 2,506,151 on May 2, 1950; and other subject-matter herein disclosed is claimed in our co-pending application Serial No. 148,228 filed March '7, 1950.
The primary objects of the invention are to provide an improved chair of the retracting type wherein the occupant may move the seat rearwardly in order to permit others to pass in front of him without his having to rise from the seat; to provide such a retracting chair in which the space beneath the seat is entirely free of mechanism thus to facilitate cleaning of the floor beneath the seat and thus to eliminate any projecting parts which might detract from the comfort or safety of a patron in the rear of the chairgto provide such a retracting chair in which the'seat is pivotally mounted on seat carriers so that the seat may be turned to a raised position of nonuse thus to provide a maximum of space in front of the chair for the ingress and egress of patrons between the rows; to provide such a chair in Which the seat carriers are mounted on the standards for quiet and smooth forward and rearward movements; and in general to provide such a retracting chair which is eflicient in operation, reasonably economical in manufacture and attractive in appearance.
An illustrative embodiment of the invention is shown in the accompanying drawings, wherein:
Figure 1 is a side elevational View of the left hand side of the chair, the chair seat and back being shown in forward, unretracted positions;
Figure 2 is a fragmentary front elevational view of the same; and
Figure 3 is a side elevational View similar to Figure 1 and showing the various parts in their rearward or retracted position, I 7
Referring now in detail to these drawings, the chair shown therein is mounted on a frame com prising spaced, upright, chair-supporting standards ID. The term frame as used herein and in the appended claims is intended to include spaced standards as shown and also a unitary structure having cross braces or other connections. The standards It are provided with conventional arm rests H on the upper ends thereof, and each standard may be so cast as to form a common support for the adjacent side of chairs installed in a row.
On the inner face of each standard II] is mounted a rearwardly-downwardly sloping guide rod I2, said rods being installed on the standards by passing them forwardly through lugs 13, seating the forward ends in sockets l4, and turning screws IS in the lugs I3 into engagement with the rearward ends of the guide rods. It will be understood that the mechanisms at opposite sides of the chair are identical except as to right-hand and left-hand formation, although only the mechanism at the left-hand side of the chair is shown in the drawings.
Seat carriers H5 are provided with sleeves I1 slidably disposed on the guide rods l2 for forward and rearward movement on said rods. A bracket I8 is mounted on each seat carrier I 6, and an upholstered chair seat 19 is pivotall mounted on the brackets 58 so that the seat is turnable about a horizontal axis to the lowered position of use shown or to a raised position of non-use (not shown), and the seat is also movable forwardly and rearwardly with the seat carriers Hi to forward and retracted positions.
The chair back comprises a sheet metal back plate 20 whose horizontal cross-section is generally of forwardly opening U-shape, and an upholstered back 2| secured within the'back plate. The chair back is pivotally connected at its opposite sides to the rearward ends of the seat carriers l6, by means of extensions 22 at the lower forward corners of the back plate 20 which are pivottally connected at 39 to upwardly extending arms 23 at the rear of the seat carriers. Back-supporting links 24 have their lower ends pivotally connected at 40 to the standards [0 and their upper ends pivotally connected at 4| to the sides of the back plate 20 for suppporting the chair back for forward and rearward movements and for turning movement about a horizontal axis concentric with the pivotal connections 4| of the back plate 20 to the links 24,
In order that the sleeves I! may travel freely along the guide rods I2 with no binding action, it is important that the rearward ends of the seat carriers travel in paths substantially parallel to the guide rods l2, as indicated by the double arrow in Figure 1. This is accomplished by means of control links 25 pivotally connected at 42 to the upper portions of the standards l0. Connecting links 26 are pivotally connected at 43 to the lower ends of the control links 25 and are pivotally connected at 44 to bracing members 2'! rigidly secured to opposite sides of the back plate 20. Other connecting links 28 are pivotally connected at 45 to the medial portions of the control links 25 and are pivotally connected at 46 to the medial portions of the back-supportin links 24. It will be seen from a comparison of Figures 1 and 2 of the drawings, that when links 24 move rearwardly about their pivots 40, they carry with them the upper part of the chair back pivoted to said links at 4|. The pivotal connections at 39 between the lower part of the back and the seat carriers H5 must move approximately twice as far as the connections at 4|, and in substantially straight paths in order to maintain the seat at the same inclination and give it the required distance of travel, and also in order to turn the back to a nearvertical position. This movement of the connections 39 is effected by links 28, and 26. Links 28 bein connected at 46 to links 24 nearest the latters free ends 4| and being connected to links 25 at nearest their fixed ends 42, the free ends 43 of links 25 are caused to move faster and farther than the free ends 4| of links 24, and this movement of links 25 is transmitted to the lower part of the back and to the seat carrier through the short links 26. The seat carriers l6 are thus moved in substantially straight paths parallelto the guide rods l2 and there is therefore no binding action between the sleeves and the guide rods I2, If desired a lubricant may be applied to the guide rods 2 to further reduce friction.
Forward and rearward movements of the seat carriers are limited by means of rubber cushion 7 front stops 29 and similar rear stops 38 on the standards Ill, which stops are contacted by front bumpers 3| and'rear bumpers 32 respectively on the seat carriers.
It willbe seen that as the seat is retracted by the occupant to increase the space in front of the chair, the back is moved rearwardly and also angularly turned to a near-vertical position so that a minimum of space to the rear of the chair is required for retraction.
While but one specific embodiment of the invention has been herein shown and described, it will be understood that'numerous details may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.
We claim:
1. In a chair, a frame having guide rods at opposite sides thereof, seat carriers having sleeves on their forward ends mounted on the guide rods for forward and rearward movement thereon, a chair seat mounted on the carriers, a chair back pivotally connected at its opposite sides to the rearward ends of the seat carriers, back-supporting links having their lower ends pivotally connected to the frame and their upper ends pivotally connected to opposite sides of the chair back, control links pivotally depending from the upper portions of the frame forwardly of the back-supporting links, connecting links associating the lower ends of the control links with the back and other connecting links associating the medial portions of the control links with the medial portions of the back-supportin links wherebyv the pivotal connections of the back to the seat carriers are caused to move in straight paths parallel to the guide rods, and stop means for limiting 4 the forward and rearward movements of the carriers.

I
