A seat, such as a chair or stool, is disclosed and comprises a frame including at least one leg, an undercarriage which is configured to receive the leg, and a seat pan. The seat pan is rotatably mounted to the undercarriage, wherein the seat pan is rotatable about an axis of rotation relative to the undercarriage.The undercarriage also includes a recess and a resilient component in the recess, while the seat pan includes a stop located on a bottom surface of the seat pan. On rotation of the seat pan relative to the undercarriage, such as may occur when the person seated leans forward or back, the resilient component is compressed between the undercarriage and the stop. In one embodiment, an axle passes through the axis of rotation and connects the legs, and potentially backrest if present, to the undercarriage.

A chair includes a backrest and a backrest frame. The backrest is configured to support a back of a user of the chair. The backrest frame supports the backrest. The backrest frame includes a right bar-shaped member, a left bar-shaped member, and an upper bar-shaped member. The right bar-shaped member supports a right side of the backrest. The left bar-shaped member supports a left side of the backrest. The upper bar-shaped member supports an upper side of the backrest. Further, the upper bar-shaped member protrudes so as to be convex toward a rear side, and connects the right bar-shaped member and the left bar-shaped member.

A seat includes a seat base including a seat base linkage, a backrest including a seat back linkage, a connector rod, and a frame. The seat base linkage is pivotally secured to the seat back linkage at a first pivot point. The seat base linkage is pivotally secured to the connector rod at a second pivot point. The connector rod is pivotally secured to the frame at a third pivot point. The seat back linkage is pivotally secured to the frame at a fourth pivot point. When the seat is adjusted between an opened position and a closed position, the first pivot point describes the arc of a circle.

A chair comprising two facing and cooperating sidepieces (11), bar-type connection means to correctly and stably distance the two sidepieces (11), and, during use, a backrest (13) and a seat (12); the bar-type connection means, the backrest (13) and the seat (12) connect the two sidepieces (11) transversely in a stable manner.

To provide a chair which is excellent in workability of nesting and unnesting, and is convenient to use as a chair.SOLUTION: A chair includes front legs 1, rear legs 2, a seat 3, and a backrest 4, and a horizontal interval between the front legs 1 is narrower than a horizontal interval between the rear legs 2. Thus, chairs can be nested back and forth. The seat 3 has tapered parts 15 whose lower surfaces are inclined planes 14 and thick parts 16 continuing to the same via step parts 17. A front end of the inclined plane 14 of the rear seat 3 is on a rear boss part 11 of the front seat 3, so that the back seat 3 is flipped up. Thus, the chairs can be nested without requiring the seat 3 to be flipped up each time. When the chairs are unnested, the seats 3 automatically shift to a use state to keep horizontal postures. Therefore, it is convenient to use.SELECTED DRAWING: Figure 3

To provide a technique for stacking chairs with optional parts attached to the chairs. [Solution] The optional part has an upper part, a lower part located below the upper part, and a fixing part that fixes the upper and lower parts to a stackable chair. The upper part has at least portions arranged opposite each other across an axis, forming an entrance for putting in and taking out a predetermined item. The lower part covers at least one of the side and bottom surfaces of the predetermined item, and the front and rear sides of the lower area of ​​the upper part in the fore-and-aft direction of the chair are open. In the stacked state, the first optional part and the second optional part are configured so that a portion of the upper part of the second optional part overlaps above the first optional part, and the lower part of the second optional part overlaps in front of the first optional part.

To provide a fixture that offers excellent ease of installation and features a component mounting structure that allows for secure and firm fixation. [Solution] The fixture 1 according to the present invention comprises a mounting member 30 and a member to be mounted 28 to which the mounting member 30 is fixed. The mounting member 30 has a locking projection 32 erected at a predetermined position, and the member to be mounted 28 has a locking hole 28a into which the locking projection 32 enters. The mounting member 30 and the member to be mounted 28 are fixed to each other by inserting a pin member 34 into the locking projection 32 with the locking projection 32 entered into the locking hole 28a, thereby pushing the locking projection 32 radially open.

A chair set formed to be stackable is provided. The chair set includes a chair and an optional member. The optional member is formed to allow a given object to be put in and taken out of it along an axis extending in a substantially up-down direction of the chair. The optional member includes an upper portion, a lower portion, and a fixing portion. In a stacked state in which a second chair is stacked on a first chair, a first optional member fixed to the first chair and a second optional member fixed to the second chair are stacked such that the upper portion of the second optional member partially overlaps above and with the first optional member and such that the lower portion of the second optional member overlaps with a front-side part of the first optional member.

To provide a chair that can prevent a garment of a seated person from being caught when a seat body is in a use posture, and can make the external appearance excellent.SOLUTION: A chair includes a seat body 3 and a leg body 2. The leg body can switch the seat body between a use posture and a storage posture. The leg body has a pair of front legs 21 and a pair of rear legs 22 separated in a chair width direction. The front and rear leg pair at one side in the chair width direction and the front and rear leg pair at the other side in the chair width direction are connected by a horizontal connection rod 24 extending in the chair width direction. The seat body includes a frame-shaped frame and a swelling beam. The frame-shaped frame has a front portion support rod, a rear portion support rod, and left and right side portion support rods. The swelling beam is connected to the front portion support rod and the rear portion support rod, is arranged in an inner area in the chair width direction of the pair of side portion support rods, and has an intermediate area in a front-back direction swelling to an opposite side to a seat side of a seating face. The swelling portion of the swelling beam is abutted on a top face of the horizontal connection rod in a state that a seat plate is in a use posture.SELECTED DRAWING: Figure 1
