Abstract
The invention discloses a kind of mechanical high inclination-angle backrest seat board link gear, including base plate assembly and backrest, also include the backrest rotating shaft and the roller that are installed on hold-down support, wherein, roller supporting in the lower section in base plate assembly centre position, base plate assembly be positioned over roller top and it is slidable against, backrest rotating shaft is fixed on the hold-down support, backrest is placed in backrest rotating shaft and rotatable relative to it, and base plate assembly is hinged with backrest.Mechanical high inclination-angle backrest seat board link gear proposed by the present invention, improves the reliability of riding comfort and product, while avoiding the situation that the backrest under human bady gravitational effect automatically returns to vertical state.
Description
Technical field
The present invention relates to armchair structure technical field, more particularly to a kind of mechanical high inclination-angle backrest seat board gear
Structure.
Background technology
At present, many backrests can adjust reclining angle, and people can adjust different angles and allow and oneself be seated more
Comfortably.Seat design also has link gear, i.e., movable seat when can drive backrest motion, but, existing seat
The lifting of chair back comfortableness is limited, and mechanics principle has dead point.In addition, existing link gear is present in human bady gravitational effect
Under, even if hydraulic lock/gas spring is not unlocked, also occur that backrest automatically returns to vertical state, so as to reduce hydraulic lock/gas
The service life of spring.
The content of the invention
It is a primary object of the present invention to provide a kind of mechanical high inclination-angle backrest seat board link gear, it is intended to avoid
Backrest automatically returns to the situation of vertical state under human bady gravitational effect.
To achieve the above object, the present invention provides a kind of mechanical high inclination-angle backrest seat board link gear, including seat
Board component and backrest, also including the backrest rotating shaft and the roller that are installed on hold-down support, wherein,
In the lower section in the base plate assembly centre position, the base plate assembly is positioned over above roller and relative the roller supporting
In it slidably, the backrest rotating shaft is fixed on the hold-down support, and the backrest is placed in backrest rotating shaft and relative to it
Rotatably, the base plate assembly is hinged with the backrest.
Preferably, the backrest is located at base plate assembly and backrest pin joint and roller and seat with the tie point of backrest rotating shaft
Between the contact point of board component.
Mechanical high inclination-angle backrest seat board link gear proposed by the present invention, overcomes on existing seat mechanics and exists
The problem at dead point, while, it is to avoid prior art backrest under human bady gravitational effect automatically returns to the defect of vertical state, changes
It has been apt to the stressing conditions of the transmission efficiency and hydraulic lock of the power of total/gas spring, has improve reliability of structure and hydraulic pressure
The service life of lock/gas spring.In addition, under the supporting role of roller, identical backrest hypsokinesis angle case, this link gear
Bigger seat board updip angle can be provided, it is more met ergonomics, seat presence comfortableness is improved to greatest extent.This
Mechanical high inclination-angle backrest seat board link gear also has the advantages that simple structure, low cost and easily realizes.
Brief description of the drawings
Fig. 1 is the structural representation of mechanical high inclination-angle backrest seat board link gear preferred embodiment of the invention.
In figure, 1- base plate assemblies, 2- backrests, 3- rollers, 4- backrest rotating shafts, 5- pin joints.
The realization of the object of the invention, functional characteristics and advantage will be described further referring to the drawings in conjunction with the embodiments.
Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
It should be noted that in the description of the invention, term " transverse direction ", " longitudinal direction ", " on ", D score, "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " are based on accompanying drawing institute
The orientation or position relationship for showing, are for only for ease of the description present invention and simplify description, are not the dress for indicating or implying meaning
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limit of the invention
System.Additionally, term " first ", " second " etc. are only used for describing purpose, and it is not intended that indicating or implying relative importance.
Reference picture 1, in this preferred embodiment, a kind of seat board link gear of mechanical high inclination-angle backrest 2, including seat board
Component 1 and backrest 2, also including being installed on hold-down support（Not shown in figure）On backrest rotating shaft 4 and roller 3, wherein,
Roller 3 is supported in the lower section in the centre position of base plate assembly 1, and base plate assembly 1 is positioned over the top of roller 3 and can be slided relative to it
Dynamic, backrest rotating shaft 4 is fixed on hold-down support, and backrest 2 is placed in backrest rotating shaft 4 and rotatable relative to it, base plate assembly 1 with
Backrest 2 is hinged.
Roller 3 is rotatable relative to hold-down support, and roller 3 is supported to base plate assembly 1 in vertical direction.
Backrest 2 is located at base plate assembly 1 with the pin joint 3 of backrest 2 and roller 3 and seat board group with the tie point of backrest rotating shaft 4
Between the contact point of part 1.This mechanical seat board link gear of high inclination-angle backrest 2 can be used for aircraft business class and economy class seat
Chair, railroad train seat etc..
The motion principle of this mechanical seat board link gear of high inclination-angle backrest 2 is as follows：When backrest 2 is around backrest rotating shaft 4
In the direction of arrows backward hypsokinesis when, pin joint 3 of the backrest 2 by it with base plate assembly 1 drives the rear end of base plate assembly 1 to turn around backrest
Axle 4 does downward circular motion, and under the supporting role of roller 3, base plate assembly 1 is upturned using roller 3 as fulcrum front end,
The top rade increase of base plate assembly 1, such as Fig. 1 dotted portions are 50 ° of 2 hypsokinesis of backrest, 11 ° of the updip of base plate assembly 1.When people's body weight
When power acts on 1 front end of base plate assembly, the action effect of the hypsokinesis applied to backrest 2 by leverage, rather than turning forward
Effect, therefore avoid old structure backrest 2 under human bady gravitational effect and automatically return to the defect of vertical state.
The seat board link gear of mechanical high inclination-angle backrest 2 that the present embodiment is proposed, overcomes on existing seat mechanics
There is a problem of dead point, while, it is to avoid prior art backrest 2 under human bady gravitational effect automatically returns to lacking for vertical state
Fall into, improve the stressing conditions of the transmission efficiency and hydraulic lock of the power of total/gas spring, improve reliability of structure and
The service life of hydraulic lock/gas spring.In addition, under the supporting role of roller 3, the hypsokinesis angle case of identical backrest 2, this connection
Motivation structure can provide bigger seat board updip angle, it is more met ergonomics, seat presence is improved to greatest extent and is relaxed
Adaptive.This mechanical seat board link gear of high inclination-angle backrest 2 also has the excellent of simple structure, low cost and easy realization
Point.
The preferred embodiments of the present invention are these are only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
The equivalent structure transformation that bright specification and accompanying drawing content are made, or other related technical fields are directly or indirectly used in,
Similarly it is included within the scope of the present invention.
