In addition, this mounting base is also an element of tuning the overall design, which reduces its reliability due to movable elements. (RU 2664225, http://www1.fips.ru)

Disclosure of the invention.

The objectives of the claimed solution is to develop a fastener design that provides the user with the ability to install additional devices on an office chair with a more evenly distributed load compared to the analogue.

As a user in the framework of this patent, it is worthwhile to understand a user who needs to install additional equipment on an office chair.

The tasks are achieved due to the fact that the claimed mount is a structure that is installed under the seat of the chair, directly on the mount legs (legs), while in contrast to analogues it has a more reliable design. The claimed fastening provides the user with the opportunity to install additional devices on his office chair. To install the claimed fastening does not require any structural modifications of the chair before installing the claimed fastening on it.

To install the claimed fastening, an office chair should consist of at least a seat, fastening the legs (legs) and legs (legs). The presence of additional backrests, armrests, rollers with a spider, gas lift, swivel mount does not interfere with the installation of the claimed mount.

It should be noted that under the attachment of the legs (legs) should be understood any device that connects the seat with the leg (s). This can be a gas lift piastra, a rotation mount, a simple mount connecting the leg (s) with the seat, bracket, etc.

The mount has a simple structure providing a housing (1) hollow inside FIG. 7, 8, 10 and in profile section having the shape of a rectangle or circle.
