Description
Technical field
The invention belongs to vehicular spare parts field, specifically refer to that a kind of backrest lifts unlocking type truck central seat.
Background technology
Motor-vehicle seat system is for supporting to driver in car, and under the prerequisite that guarantees convenient turnover and driver behavior, provides actv. constraint, seat system that the controllability that driver expects and the comfort of driving over a long distance should be provided.At closing of the door state, in the whole adjustment travel of seat, the operation of seat system should be suitable for all bodily form motorists and carry out control manipulation intuitively.Compare general truck and only have positive assistant driver seat, the configuration of central seat has increased the taken member's of truck quantity, and actv. utilizes interior space more.
The automotive seat that now use are handle locking type seat, its component part comprises back of seat, Chain cushion, mounting bracket, recliner, regulating handle, and wherein recliner is realized the turnover of back of seat, the function of locking by regulating handle.
Handle locking type seat, needs to have recliner on seat, cost is higher; The position of central seat and structure are unfavorable for the layout of control apparatus, easily cause handle to regulate power large, less with interior trim gap, are unfavorable for the problems such as operation.
Summary of the invention
The object of this invention is to provide a kind of plug-in locking structure, make seat in the situation that not increasing recliner, just can realize the locking of back of seat and lift release; Seat cost, weight are controlled; Without regulating handle restriction, make the layout of seat can not consider the requirement of operational space.
The present invention is achieved by the following technical solutions:
Backrest lifts unlocking type truck seat, includes Chain cushion, the cushion skeleton structure of support seat cushion, back of seat, the backrest frames structure of support seat chair back;
The both sides of described cushion skeleton and backrest frames contact edge are respectively provided with arc convex, and the center line extended line of described projection is parallel with the face that backrest frames and back of seat form;
On described arc convex, be provided with the limit shaft vertical with the face of arc convex, between limit shaft and the top of arc convex, be provided with guide groove; The center line of the center line of described guide groove, spacing axis of spindle and arc convex overlaps;
The nearly lower end, two sides of described backrest frames is respectively arranged with S. A., and S. A. coordinates with guide groove, to guarantee that backrest frames can rotate around S. A. limited angle;
The lower end of two sides of described backrest frames is respectively arranged with position-limited trough structure, and limit shaft can enter in position-limited trough.
Described guide groove is long waist type.
Described arc convex is inserted into the inner side, two sides of backrest frames.
In the side of described position-limited trough and backrest frames, approach back of seat side end and be set to arc angling.
The degree of depth of position-limited trough is greater than the diameter of axle length of limit shaft.
The lower surface of cushion skeleton is provided with mounting bracket.
The invention has the beneficial effects as follows:
By S. A. and coordinating of limit shaft, position-limited trough, realize the locking of backrest; After backrest upwards lifts, latch functions disappears, and backrest can freely put down.Do not need recliner to realize the turnover of backrest, latch functions; Be conducive to seat cost control and lightweight, be conducive to the clearance control of seat and its Surrounding Parts.

The specific embodiment
Describe by the following examples technical scheme of the present invention in detail, should be understood that, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
As shown in Figure 1, backrest lifts unlocking type truck seat, includes Chain cushion 4, cushion skeleton 7 structures of support seat cushion, and Chain cushion 4 is fixed in cushion skeleton 7 structures.Back of seat 1, backrest frames 6 structures of support seat chair back, back of seat 1 is fixed in backrest frames 6 structures; Cushion skeleton structure and backrest frames structure are metal material manufacture.
Described cushion skeleton 7 is respectively provided with arc convex 10 with at least both sides of backrest frames 6 contact edges, in other embodiments, is also provided with arc convex in centre; The center line extended line of described arc convex is parallel with the face that backrest frames and back of seat form, and can guarantee the angle between back of seat and Chain cushion like this, is beneficial to the design that conforms to Human Physiology curve.Each arc convex is all parastate, and arc convex is plank frame.Described arc convex 10 is inserted into 11 inner sides, two sides of backrest frames 6.
On described arc convex 10, be provided with the limit shaft vertical with the face of arc convex 9, the top wire length of both sides limit shaft is greater than the length of backrest frames dual-side outside face line.Between limit shaft 9 and the top of arc convex 10, be provided with guide groove 13, described guide groove 13 is long waist type.The center line of the center line of described guide groove, spacing axis of spindle and arc convex overlaps;
The 11Jin lower end, two sides of described backrest frames 6 is respectively arranged with S. A. 8, S. A. can be an axle construction, also can be two axle construction, S. A. 8 coordinates with guide groove 13, S. A. can be in External Force Acting lower slider in guide groove, and S. A. is to guarantee that backrest frames can rotate around S. A. limited angle;
The lower end of two sides 11 of described backrest frames 6 is respectively arranged with position-limited trough 12 structures, and limit shaft 9 can enter in position-limited trough 12.In the side of described position-limited trough and backrest frames, approach back of seat side end and be set to arc angling.
