Definitions
- the invention relates to a device for regulating the inclination of the seat back of a seat, which is characterized in that it functions without manual or motor assistance.
- the seat backrest angle is adjusted individually depending on the weight of the seat user without the seat user having to use any lever or motor function.
- the basis of the invention is the determination of the load by the weight of the seat user acting on the seat surface B and the sensor-based detection of the seat load by means of a sensor system A in the form of a linear distance measurement and the transfer of the length distance resulting from the seat load by means of a transfer means C to a resilient element D.
- the resilient element consists of a reversibly compressible and re-expandable flexible material which is compressed to a greater or lesser extent relative to the length of the distance sensed by sensors acting on the seat under load.
- the resilient element is located between at least two clamping jaws or clamping surfaces 14. In accordance with the distance covered by the sensor system and transferred to the resilient element by the transfer means, the resilient element is more or less compressed and the components connected to the seat back are spread more or less, which is directly expressed as the angle of the seat back of a seat.
- the movement dynamics of seats requires, depending on the weight of the person using the seat, a correspondingly regulated tension design of spring systems in order to push the seat into position with the body weight, or for that Resetting to a different position, for example to the vertical.
- the problem of manually regulating the seat backrest inclination is often difficult.
- the seat inclination setting is often manipulated while driving, which distracts the driver's driving style and can therefore possibly trigger an accident.
- spring tension systems coupled to the seat and the backrest light or dainty, non-muscular people can hardly manipulate such a system because they cannot push the backrest back.
- Heavy, muscular types on the other hand, have the feeling of drifting backwards when they want to change the backrest angle.
- the object of the invention is therefore to regulate
- the seat user should enjoy non-tiring seating comfort and the seat back regulation should be self-regulating, that is, without the aid of manipulable or motorized aids,
- the basis of the invention and primary sensor for achieving the object of the invention is the weight detection of the user of the seat.
- the detected weight value is sensed as a distance traveled and by means of a transfer system, for example in the form of a distance direction converter and one
- Push rod transferred to a resilient element, which is positioned between at least two clamping jaws or clamping disks or their combinations, via which the seat backrest angle is adjusted directly via legs connected to the clamping jaws or also by means of combined systems, where one leg represents the seat back and the counter part can be a molded seat part.
- the weight sensor system can be determined pneumatically or hydraulically and transferred to the spring element.
- the detected weight as a sensor basic parameter for regulating the movement dynamics automatically acts as a distance on the following elements in such a way and automatically that the device according to the invention functions without any external energetic influence or manipulation aid.
- FIG.1 shows the basic principle of the inventive device with the resilient element D in the position, as with heavily loaded seat 1, with clamping jaws 14 and in this constellation with leg 15, in the double function as a simultaneous clamping part.
- E is the clamping gap between the jaws 14 and in this case leg 15
- FIG 3 shows the two representations of the resilient element D at the corresponding loads B at low loads - dashed position of the element D1 and at heavy loads - continuous lines - of the element D2 according to the distance distances detected by the sensor system A, which are transferred by means of C to the Resilient element on the jaws 14 cause the backrest inclination.
- Fig. 4 shows a chair with a seat and the inventive design variant in the side view in the neutral rest position, with the seat 1, the backrest 2, the chair base 3, the support shaft 4, the seat support 5, the lower armrest 10, the push rod 7 , the resilient element D, the sensor system C with the weighing spring 9 and the rocker arms 13 located at the end of the weighing beam 12. Furthermore, the connecting axis of FIGS. 6 and 7 and the fastening support 17.
- Fig. 5 shows the construction of a chair in function, with seat load B.
- the fixed rocking axis 11 and the rocker arm 13 located at the end of the weighing beam 12 the force B acting on the seat via the distance transducer 6 on the horizontal push rod 7 taken together as transfer means C, transferred to the resilient element D.
- the distance-related weighing result which is not ascertained in terms of numbers, is transmitted to the lower arm leg 10 via the resilient element, as a result of which the seat back assumes an angle of inclination corresponding to the seat load B. In this case, for example, as in 2a.
- a minimum spring force must be applied by a resilient support element G, which is located next to the resilient element with pre-tension and which prevents the resilient element from functioning prematurely.
- the resilient element is a kind of energy storage in the compressed form. Its shape is therefore not fixed to the described wedge shape, but can be designed in different geometrical ways.
- the present inventive device leads to the simplified regulation of the seat backs conforming to the movement dynamics of the seat user. This is accompanied by a reduced material expenditure for the manufacture of the device in comparison with the prior art. In particular, because any manipulation mechanisms are omitted, as are any motors, including batteries or power supply lines, and the elimination of the associated malfunctions that require service.
- the device for regulating the inclination of the seat back most accurately reflects the subject of the invention under the term “self-regulating”.
- the exemplary figures are representative.
- the pneumatic or hydraulic longitudinal measurement is used to transfer it to the spring Element takes place, for example, by means of hermetically sealed air or liquid cushions, the necessary stroke distance for the reciprocating movement of the resilient element taking place via appropriate piston mechanisms via the media pressure and transfer lines.
- the seat support 5 performs a linear downward movement along the support shaft 4. This linear movement of the seat support 5 in relation to the support shaft 4 is illustrated in FIG. 5 by the arrow 18.
- the direction converter 6 has a two-armed angle lever 20 with a weighing beam 12 and a connecting beam 22.
- the angle lever 22 is pivotally connected in the knee area by means of a connecting axis 24 to the seat support 5 directed downward from the seat 1.
- the weighing beam 12 is attached with the rocking axis 11 to the mounting support 17, for example linearly horizontally movable, i.e. the weighing beam 12 can be pivoted about the rocking axis 11, the rocking axis 11 executing a corresponding horizontal linear movement when pivoted.
- the rocker arm 13 of the direction converter is defined between the rocker axis 11 and the connecting axis 24.
- the resilient element D On the underside of the seat 1, the resilient element D is arranged to be linearly movable, which is designed, for example, with a wedge-shaped base.
- the pointed edge of the resilient element D of a triangular base shape is designated by the reference number 26.
- the resilient element D is with dash-dotted lines in the direction of arrow 28, ie in the direction of view from below.
- the resilient element D is connected to the angle lever 20 of the direction converter 6 by means of the push rod 7, i.e. connected at its end remote from the resilient element 26 to the connecting axis 16.
- the connecting axis 24 executes a clockwise movement about the rocking axis 11.
- the connecting axis 16 executes a corresponding clockwise movement about the rocking axis 11, so that the push rod 7 performs a movement in the direction of the arrow 28.
- the resilient element D is thus moved in the direction of arrow 28.
- This movement of the resilient element D is the greater i.e. longer, the greater the weight of the seat user sitting on the seat.
- the weighing spring 9 is tensioned when the seat 1 is loaded. If the seat 1 is relieved, i.e. If a seat user leaves the seat 1, the weighing spring 9 relaxes and the resilient element D returns to its unloaded starting position.
