Show, present embodiments provide a kind of seat skeleton 100 for vehicle seat, generally may include two groups of side plate components 10
With transverse tube group 20.Lateral symmetry arrangement of two groups of side plate components 10 along vehicle seat.Transverse tube group 20 is prolonged along the transverse direction of vehicle seat
It stretches and is overlapped between two groups of side plate components 10.Every group of side plate component 10 includes lower side plate 11 and upper side plate 12.Lower 11 edge of side plate
The front-rear direction of vehicle seat extends.One end of upper side plate 12 is connected (referring to Fig. 3), separately with the backrest frames 200 of vehicle seat
One end is connected with lower side plate 11 close to one end of backrest frames 200.
The seat skeleton 100 for vehicle seat of the present embodiment, will 11 ' additional seat lower bracket 12 ' of seat side plate in the prior art
Structure be changed to the upper side plate 12 being vertically connected with and lower 11 structure of side plate, can effectively improve on the front-rear direction of vehicle seat
Rigidity is conducive to the raising of the overall stiffness of vehicle seat.
Further, seat skeleton 100 is changed to present split type upper side plate 12 by the seat side plate 11 ' of original integral type
With lower side plate 11, the size of individual part is reduced, convenient for the exploitation of mold.And the upper side plate 12 of split type setting is under
Its size can be respectively set in side plate 11, such as its thickness can according to need and be configured, and then meets its specific operating condition
It is required that.
Optionally, the thickness of upper side plate 12 is set greater than the thickness of lower side plate 11.Under normal circumstances, seat skeleton 100
Severe elsewhere with the stress condition ratio of 200 junction of backrest frames, therefore can be by the thickness of upper side plate 12 in design
Degree is set greater than the thickness of lower side plate 11, that is to say, that it can only reinforce the thickness at upper side plate 12 when increasing intensity, and
The thickness of entire seat side plate 11 ' is not needed to increase, therefore the present embodiment is conducive to light-weight design.
In one embodiment, upper side plate 12 is mutually lapped in junction with lower side plate 11 and is connected by fastener.Such as Fig. 2
Shown in embodiment, upper side plate 12 is overlapped on the outside of lower side plate 11, is equipped with multiple companies at the two overlapped lap position
Hole 101 is connect, for wearing fastener, such as bolt or rivet, upper side plate 12 and lower side plate 11 are linked together.
As shown in figure 3, the upper end of the upper side plate 12 of the seat skeleton 100 of the utility model is connected in backrest, lower side plate 11
Downside is fixedly connected in sliding rail 300.
In one embodiment, as shown in Fig. 2, the downside of lower side plate 11 is configured to, both ends are downwardly convex, middle part is recessed upwards
Shape, the bottom at the both ends of 11 protrusion of lower side plate with the sliding rail 300 of vehicle seat for being connected.That is, the present embodiment
The both ends of downside of lower side plate 11 be equivalent to seat lower bracket 12 ' (referring to Fig. 1) in the prior art, the both ends bottom of the protrusion
It is provided with mounting hole 102, for wearing fastener so that seat skeleton 100 to be connected to the sliding rail 300 of vehicle seat bottom (referring to figure
3).The connection type of seat side plate 11 ' in the prior art He seat lower bracket 12 ' is changed to the lower side plate 11 of integral type by the present embodiment,
The quantity of part can be saved.
In another embodiment, as shown in Fig. 2, each the inside of lower side plate 11 is equipped with side stiffening plate 30, side is reinforced
Plate 30 is arranged close to upper side plate 12.Optionally, side stiffening plate 30 is connected by welding with lower side plate 11.As before, upper side plate 12 with
Lower 11 junction of side plate usually requires higher intensity, increases the intensity that side stiffening plate 30 is conducive to reinforce the position here,
The setting of side stiffening plate 30 can increase the lateral rigidity of a skeleton 100 simultaneously.
As shown in Fig. 2, transverse tube group 20 includes reinforcing transverse tube 21, before being overlapped in two lower side plates 11 in one embodiment
Side.Optionally, reinforce transverse tube 21 to be hollow circular-tube and be connected by welding with lower side plate 11.By before two lower side plates 11
Side overlap joint reinforces transverse tube 21, can be further improved the lateral rigidity of entire seat skeleton 100.Will reinforce transverse tube 21 be arranged to it is hollow
The shape of round tube can mitigate its weight while reinforcing its rigidity as far as possible.Side stiffening plate 30 and reinforcement transverse tube 21 pass through
The mode of welding connects, it is only necessary to increase positioning on the basis of original skeleton welding tooling, it is simple easy to produce.
In another embodiment, as shown in Fig. 2, transverse tube group 20 further includes a transverse tube 22 and preceding transverse tube 23.Seat transverse tube 22 is set
It is placed in the close position with upper 12 junction of side plate of lower side plate 11.Preceding transverse tube 23 is set to the front side top of lower side plate 11.It can
Selection of land, as shown in Fig. 2, hollow circular-tube can be used in seat transverse tube 22, preceding transverse tube can use Hollow cuboids.
And the seat skeleton 100 of the present embodiment is additionally arranged simultaneously by the way that split type lower side plate 11 and upper side plate 12 is arranged
Side stiffening plate 40 reinforces transverse tube 21, so that the mode value of entire chair framework 1000 improves 2Hz or more, effectively prevents sending out
Chair framework 1000 generates covibration when motivation generates vibration, avoids occupant's bodies such as output nausea after for a long time by bus
Discomfort improves the comfort of entire seat.
The utility model additionally provides a kind of chair framework 1000 for vehicle seat, as shown in figure 3, the chair framework
1000 include the seat skeleton 100 in backrest frames 200, sliding rail 300 and any of the above-described a embodiment, the upper side plate of seat skeleton 100
12 one end is connected with backrest frames 200, and the downside of the lower side plate 11 of seat skeleton 100 is connected with sliding rail 300.
Generally, the external packet of the chair framework 1000 is equipped with soft cushion, for providing support, sliding rail for passenger
300 lower part is connected with the floor of vehicle, and the back-and-forth motion of vehicle seat may be implemented by the sliding of sliding rail 300.Seat skeleton
To be rotatably connected between 100 and backrest frames 200, the angle between seat cushion of backrest is may be implemented in the relative rotation of the two
It adjusts, more to meet the sitting posture requirement of human comfort.
The seat skeleton 100 of the chair framework 1000 of the present embodiment, will 11 ' additional seat lower bracket 12 ' of seat side plate in the prior art
Structure be changed to the upper side plate 12 being vertically connected with and lower 11 structure of side plate, can effectively improve on the front-rear direction of vehicle seat
Rigidity is conducive to the raising of the overall stiffness of vehicle seat.
Further, seat skeleton 100 is changed to present split type upper side plate 12 by the seat side plate 11 ' of original integral type
