Chair having a seat whose position is adjustable description/claims

1. Field of the Invention

The present invention relates to a chair and, more particularly, to a chair having a position adjustable function.

2. Description of the Related Art

A conventional chair comprises a stand, a plurality of support legs mounted on the lower end of the strand, a support base mounted on the upper end of the stand, a backrest mounted on the support base, and a seat mounted on the support base and perpendicular to the backrest. However, the seat and the backrest are fixed so that a user cannot adjust the position of the seat relative to the backrest according to the practical requirement, thereby easily causing an uncomfortable sensation to the user when the size of the chair is not suitable for the user's stature.

In accordance with the present invention, there is provided a chair, comprising a stand, a support base mounted on the stand, a backrest mounted on the support base, a fixed bracket pivotally mounted on the support base, a movable bracket movably mounted on the fixed bracket, and a seat mounted on the movable bracket to move with the movable bracket.

The primary objective of the present invention is to provide a chair having a seat whose horizontal position is adjustable.

Another objective of the present invention is to provide a chair, wherein when the movable bracket is unlocked from the fixed bracket, the movable bracket is movable relative to the fixed bracket so that the seat is movable relative to the stand and the backrest to adjust the position of the seat relative to the stand and the backrest according to a user's requirement, thereby providing a comfortable sensation to the user.

A further objective of the present invention is to provide a chair, wherein the user only needs to pull the holding portion of the control handle upward to adjust the position of the seat, so that the position of the seat is adjusted easily and quickly, thereby facilitating the user adjusting the position of the seat.

A further objective of the present invention is to provide a chair, wherein the seat is fixed after the force applied on the holding portion of the control handle is removed, so that the user only needs to release the holding portion of the control handle to lock the seat automatically, thereby saving the user's energy.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
