Description
- The invention relates to a sitting apparatus having synchronous mechanism providing body ergonomy.
- The invention particularly relates to a sitting apparatus consisting of seat and back rest containing several parts, providing harmony of the cavity of sitting person as per his/her weight and size, taking its former shape after the load is removed when the sitting is over, where the said parts fitting to the sitting area of the person are capable to move synchronously in respect to each other as per body structure.
- The invention also consists of a sitting apparatus designed as at least three-part seat reducing the pressure at sacral part during sitting.
- Today several chair and seat embodiments are used in enclosed locations such as home, office, conference and seminar halls, cinemas, theatres and similar locations. Such chair and seats have been designed in various ways to ensure comfort of people. Particularly, people sitting on seats in the locations such as conference halls, cinema, theatre halls for long time periods suffer from pain in back and waist parts. The biggest reason for it is that the back rest of such seats are fixed and therefore the seat fails to fully fit to the back parts of person sitting on it.
- There are also types of seat s which are capable to move as per back parts of the sitting person. However, this movement occurs in a manner the motion axis is the part where the back rest part meet the sitting part. In other words, the pack part moves as a whole. For that reason, back and waist part of the person cannot become fully in harmony with the back rest part and the person usually suffers from pains and disorders particularly in waist part.
- Moreover, seat parts of such seats and chairs are also made as a single part. For that reason, as the part where the body contacts the seat part does not contact onto the seat ergonomically, it causes disorders in persons sitting for long time. Such disorder occurs in various parts of the body but long time sitting particularly cause pressure on sacral part of the user.
- No patent application for product similar to the one being subject of the invention has been seen. However, patent application no.
EP 1301107 discloses an ergonomic office chair with an extending foot. The position of the outstretched hand of a user in relation to the table hardly changes, while the seat moves back and forth on the chair and the backrest tilts. The chair retains its normal function as long as the back is extensively tilted. However, the chair contains a backrest of one single part and a seat part. - A therapeutic chair is also known from
EP 1 486 140 A1 . - In conclusion, the need for a sitting apparatus eliminating the above mentioned problems and disadvantages, consisting of multi parts, containing seat and back rest part, and where the pats are capable to move synchronously with each other in harmony with body structure and inadequacy of the existing solutions have made necessary to make development in the related art.
- From the current status of the related art, the purpose of the invention is to develop a sitting apparatus consisting of seat and back rest containing multi parts which are capable to make synchronous movement as per each other in harmony with body.
- Another purpose of the invention is to enable the person to sit on the back rest and seat part of the sitting apparatus ergonomically by help of the synchronous movement of seat and its back rest consisting of multi parts in respect to each other. In addition, the pressure on the sacral part of the person is reduced by the medium seat part provided in middle part of the double seat of the sitting part. The synchronous movement of back rest and seat consisting of several parts ensures full grasp of the body of the sitting person. Alternatively the synchronous movement of back rest and seat consisting of four parts ensures full grasp of the body of the sitting person.
- A further purpose of the invention is to prevent the health problems that might occur to the back and waist parts of people sitting on the seat for long time particularly in conference and seminar halls, cinema, theatre and other similar public locations.
- Another purpose of the invention is to provide a sitting apparatus taking form in harmony with the sitting area of the sitting person and taking its former form when the sitting person stands upon end of sitting action and thus providing protection of sacral part.
- Another purpose of the invention is to prevent the health problems that might occur to back and waist parts by means of protection of the sacral part.
- In order to achieve all advantages mentioned above and to be understood better with the details given below, the invention is a sitting apparatus according to claim 1 containing two seat parts located on right and left and moving member fitting to sitting area of the sitting person and moving in harmony within itself on the seat profile, medium part located on the spring member moving up and down and thus preventing pains that might occur on back and waist part by reducing the pressure on the sacral part, providing a high level of ergonomy and providing comfort of person.

Figures 1 and2 , the sitting apparatus (30) in general; consists of a foot (34) of star shape containing wheels (59), a sitting part (33) located on the foot (34), a back rest part (32) connected to the sitting part (33) and where the sitting persons lean his/her back, head rest part (1) of adjustable height located on upper part of the back rest (32) for head resting of the sitting person, and arm rests (35) fixed to side parts of the sitting part (33) by means of arm rest connection members (23). - Back rest part (32) consists of two back rest parts (37) connected onto back rest carrying profile (36) in a manner enabling limited rotation motion. The connection between the back rest parts (37) and back rest carrying profile (36) is provided by means of connection members (40) allowing limited rotation motion. Preferably four back rest connection members (40) are used. Back rest connection members (40) are connected to the back rest parts (37) by means of bolts (41). Motion limiting pins (42) located on the back rest connection members (40) are used in order to limit the rotation motion on the back rest carrying profile (36) of the back rest parts (37). In addition, back resting parts (38) are located on the back resting parts (37) for back resting of the person. The number of back resting part (38) is four, which can be increased or decreased.
- Back resting parts (37) are interconnected by means of a sheet spring (43) through the connection points (39). Sheet spring (43) is of an elastic structure and when the person leans against the back rest parts (37), collective synchronous motion of the back rest parts (37) is provided. Thus back rest parts (37) provide ergonomy by means of synchronous motion fitting to back structure of the sitting person. Connection sheets (44) and connection members (45) which are preferably bolts are used for connection of sheet spring (43) onto connection points (39).
- A hanger (46) is located at the rear part of the head resting part (31). The sitting person may hang his/her clothes such as coat, jacket etc. on to the hanger (46). Welding hiding members (47) fixed onto the back rest carrying profile (36) by means of connection bolts (48) are used in order to hide the welding points on the back rest carrying profile (36).
- As shown in
figure 2 , sitting part (33) consists of two sitting parts (50) connected onto the fixing spindles (26) located on the sitting part carrying profile (49) in a manner limited motion is allowed. The connection between the sitting parts (50) and fixing spindles (58) is made by means of four sitting part connection members (51) allowing limited motion of the sitting parts (50). Sitting part connection members (51) are fixed to the sitting parts (50) by means of bolts (52). Motion limiting pins (53) located on the sitting part connection members (51) provide limited rotation motion made by the sitting parts (50) on the fixing spindles (58). When the person sits on the sitting parts (50), the sitting parts (50) makes limited rotation motion around the fixing spindles (58) in a manner providing harmony with the body structure of the person.
