Description

Seating furniture with adjustable angle between seat and seatback
Technical field
The present invention relates generally to a seating furniture with adjustable angle between backrest and seat bottom.
Background
Adjustable seating furniture allow seating position to be varied by movement of various members of the piece of seating furniture.
Office chairs often have a lot of different means for adjusting the seating position, and typically allow for height adjustment of armrest, angle of backrest and height of seat bottom. Recliner chairs are aimed at providing a more relaxed sating position by allowing the seatback to be tilted backwards. Typically, armrests are provided, wherein the armrests are attached to base and seatrest.
The mechanical design of adjustable seating furniture vary a lot but typically have a lot of moving parts making them complex to assemble, less robust, and expensive. Further, it is not always desirable to have armrests on a chair, of aesthetic and practical reasons, and because it limits the design freedom of the chair.
Summary
It is an object of the present invention to provide a piece of
adjustable seating furniture allowing the seatback and seat bottom being tilted together between an upright position and a leaned back position, whilst being inexpensive and robust and not requiring use of armrests
According to an aspect of the invention, there is provided a piece of seating furniture comprising a seat bottom, a backrest, and a support frame. The backrest comprises a lower attachment portion and an upper attachment portion at a distance from the bottom attachment portion. The upper attachment portion of the backrest is hingedly attached to a back portion of the support frame, and the lower attachment portion of the backrest is hingedly attached to a back portion of the seat bottom. Further, a front portion of the seat bottom is hingedly attached to a front portion of the support frame by means of a length-adjustable connection means. When the backrest tilts backwards, it rotates about the upper attachment portion, wherein the lower attachment portion moves forward. Forward movement of the lower attachment portion of the backrest moves the seat bottom forward. Forward movement of the seat bottom is enabled by virtue of the provision of the length-adjustable connection means, movably connecting the front portion of the seat frame to the support frame. Thus, the length-adjustable connection means provides a degree of freedom needed for the backrest and the seat bottom to be able to move.
The connection means may comprise a first member and a second member movably attached to the first member for guided movement along the first member between an inner position and an outer position. The connection means may further comprise a resilient member provided between the first and second members, wherein the connection means is configured to increasingly stress the resilient member upon relative movement between the first and second members on extension of the connection means. The resilient member is compressed or stretched upon tilting back of the backrest, and the internal stress of the compressed or stretched resilient element subsequently forces the piece of seating furniture to tilt back towards an upright position. Such a connection means is robust.
The resilient member may comprise an extension spring extending internally through the first member, wherein an outer end of the extension spring is attached to an outer end of the first member, and wherein an inner end of the extension spring is attached to an inner end of the second member by means of a cross member configured to resist movement into the second member. The extension spring extends through the first member, inside the cylinder, and is thereby protected from dirt and external objects interfering with the spring during movement. Hence, operational reliability of the length- adjustable connection means is improved. Further, finger injuries are prevented, since the internal routing of the spring prevent the spring from being reached during normal operation. The cross member provides for easy assembly of the spring in the length-adjustable connection means, since it can be attached to the spring, before the spring is inserted into the first member.
The outer end of the extension spring may be attached to the outer end of the first member by means of a locking pin extending
transversely through the first member wherein said locking pin is sized and shaped such that the first member is insertable into the second member from the inner end of the second member with the locking pin installed. Such a design allows the spring to be attached to the first member and to the end plate before installation of the first member on the second member, and before tensioning the spring. Thus, it enables safe and easy installation of the spring. Once the first member has been fully inserted into the second member such that the end plate abuts the inner end of the second member, the outer end of the first member may easily be attached to the front end of the seat bottom.
The upper attachment portion of the backrest may be hingedly attached to a back portion of the support frame by means of first and second mutually snap-locking connection means provided at the support frame and the backrest, respectively. The provision of snap- locking means for joining the backrest and the support frame enables quick and easy assembly without tools, such that the piece of seating furniture may be transported in pieces and easily assembled at the site of final use of the product.
The first connection means may comprise a left and a right arm extending forwardly, wherein the second connection means comprises left and right locking means rotatably attached to the backrest and configured to receive, and snap-lock to, the left and right arm respectively of the first connection means. The left and right arms provide two separate attachment portions, and thereby improve side- to-side stability of the backrest, taking up sideways momentum.
Thus, the length-adjustable means and each respective connection between backrest and support frame may be made less strong without substantially affecting stability of the piece of seating furniture.
The second connection means may comprise left and right axes attached to the backrest, and each one of said axes be provided with an end portion configured to rotatably receive the respective locking means and to receive a respective locking clip for securing the respective locking means on the respective axis. The axes can easily be attached to the backrest to mutually define a rotational axis of the backrest. The axis and locking clips allow the locking means to be attached to the backrest without use of tools. Also, the use of axis and separate locking means provides a modularity enabling use of different locking means for different designs of the support frame, only requiring change of the locking means, and not of the axes attached to the backrest.
The first and second locking means may be provided internally of the backrest, and the backrest provided with left and right elongate openings through which the arms of the first connection means are insertable for connection of the first and second connection means.
Providing the locking means internally of the backrest hides them and thus prevents spontaneous tampering or accidental release of the locking means.
Left and right elongate bushings may be provided around the elongate openings. The bushings guide the arms of the first
connection means and protects the circumference of the openings.
The snap-locking of the first and second connection means may be provided by means of left and right snap locks provided on upper and/or lower portions of the left and right arms. Such positioning of the snap locks makes it possible to easily reach the snap lock through the respective elongate opening to release it, for service or
disassembly. For example, an ordinary screwdriver may be inserted into the elongate opening to pry open a locking tab of the snap lock. If elongate bushings are provided around the openings, they facilitate prying by protecting the surface material of the backrest from the tool used for prying.
The present invention will now be described in more detail, with reference to the appended drawings showing an embodiment of the invention. Description of figures
