Abstract

The utility model provides a folding lock component for seat of car, which is composed by the two symmetrical pairs of left and right components, wherein, a holder-connecting plate and a backrest-connecting plate hinged with each other are arranged in each pair of left and right components; a convex part connected with a car body is formed by the outward extension of the rear body of the holder-connecting plate, and a shaft is fixed on the holder-connecting plate; a set bar piece clamped with the slot of the backrest-connecting plate is arranged in each pair of left and right components, and each set bar piece is hinged with the holder-connecting plate through the shaft, and fixedly connected with the holder-connecting plate by a spring; the set bar piece of one pair of the two pair of left and right components is fixedly connected with a handle. The two pairs of connecting pieces of the folding lock component for seat of car are respectively provided with a locking mechanical system, the connection of the holder connecting plate and the car body is considered, and the stability between the backrest and a seat frame, the seat frame and the car body is improved.

Description

The novel folding lock member of automotive seat

One, technical field

The utility model relates to the seat transom, particularly automobile folding tipping-up chair transom.

Two, background technology

The transom that existing automobile folding tipping-up chair uses mainly is made up of seat connecting plate and backrest connecting plate, the seat connecting plate generally is fixed on the metal mounting of folding tipping-up chair through double-screw bolt, dispose the elasticity cushion on the metal mounting again, the backrest connecting plate is fixed on the metal back rest through double-screw bolt equally, disposes the elasticity back cushion on the metal back rest again.Hinged between seat connecting plate and the backrest connecting plate, backrest can be turned down toward the cushion direction, satisfy operating needs.Find in the use, be provided with by " row half " mode as seat in the operator's compartment, be that the backrest rear portion is under unsettled, the no support situation, because the seat connecting plate in the transom of existing seat is not taked the measure (the metal seat frame generally is to be placed on the operator's compartment base plate) that is connected with car body, thereby, the position of whole seat can be offset in vehicle traveling process at any time, is unsettled; Secondly, in the two secondary transoms of existing seat, have only a secondary transom to be provided with lockout mechanism at most, the backrest that is seat only has monolateral locking, when the automobile urgent brake car, backrest is subjected to a huge forward momentum effect, takes then can rocking forward of locking measure one side backrest is provided with, and makes the people feel that backrest lacks steadiness.

Three, utility model content

The purpose of this utility model is to provide a kind of automotive seat novel folding lock member at prior art problems and weak point, to increase steadiness between backrest and the mounting and the steadiness between mounting and the car body.This later-model purpose realizes by following design: the novel folding lock member of a kind of automotive seat, left and right two secondary members by symmetry are formed, have the seat connecting plate and the backrest connecting plate that are hinged in every secondary member, it is characterized in that described seat connecting plate rear portion stretches out, forms one and is used as and car body bonded assembly male part; Also be fixed with axle on the described seat connecting plate; Also have in every secondary member as with the notch of the backrest connecting plate dead bolt spare of clamping mutually, dead bolt spare is hinged through axle and seat connecting plate, and is fixedly connected with a spring between dead bolt spare and the connecting plate; Wherein also be fixedly connected with one handle on the dead bolt spare in the secondary member.

Have one on the male part of seat connecting plate as fixedly using the hole through attaching parts and car body hinge.

Adopt as above design, on the one hand, in two secondary transoms, all adopt lockout mechanism (the dead bolt spare of backrest both sides all is stuck among the notch of backrest connecting plate), the both sides of backrest are stuck through the backrest connecting plate, increased the steadiness between backrest and the mounting, thereby, prevented backrest because of rocking forward that situations such as sudden stop occur; On the other hand, the seat male part of connecting plate through its rear portion connects with car body, preferably adopts a connection piece and car body hinged again, like this and steadiness increase between the mounting that connects firmly of a connecting plate and the car body, and the swing in the time of can not starting again or brake.

Turn over attaching parts with existing folding and compare, this is novel following characteristics:

1, mounting is connected with car body through the seat connecting plate, is both the backrest both sides and is provided with lockout mechanism; Whole seat is more firm;

When 2, seat connecting plate and car body is hinged, can be on cushion with the backrest turnover, again with whole seat from front to back (backrest for the back, down not together) start, to vacate the under-seat base plate, as taking of fuel tank under the seat in the operator's compartment or tool box;

3, this novel situation that is specially adapted to the operator's compartment seat by " row half " setting.

Four, description of drawings

Fig. 1 Fig. 2 is respectively the block diagram of left and right two secondary members of the present utility model;

Fig. 3 is the block diagram of member shown in Figure 1 when the backrest connecting plate is turned down forward.

Five, the specific embodiment

Fig. 1 illustrates, and the shape of seat connecting plate 2 is similar to " Z " font, and its rear portion stretches out, and forms male part, has on this male part to fix and uses hole 2c, can adopt an attaching parts and car body to be hinged in addition.Be fixed with axle 6 on the seat connecting plate, backrest connecting plate 1 is hinged on axle 6, has bayonet socket 1c and notch 1d on the backrest connecting plate, and bayonet socket 1c is suitable with the registration mast 7 that connects firmly on end connecting plate.Dead bolt spare 3 fixing axle 8 on end connecting plate is hinged with end connecting plate, dead bolt spare with lean on connecting plate on the notch 1d effect of matching, spring 5 connects firmly between dead bolt spare and end connecting plate, also is fixedly connected with one handle 4 on the dead bolt spare.During installation, use bolt end connecting plate to be fixed on the seat metal underframe through hole 2a, 2b, again with another attaching parts such as angle bar (not shown), again the angle bar another side is fixed on the car body with on the 2c of hole at the fixing of end connecting plate through the bolt hinge, uses bolt backrest connecting plate 1 to be fixed on the metal back rest of seat simultaneously through hole 1a, 1b, when backrest is holded up, bayonet socket 1c is stuck on the registration mast 7, simultaneously, because the pulling force of spring 5 is stuck on the notch 1d the prominent pawl of dead bolt spare 3 tightly.Right side member shown in Fig. 2 is identical with left-side member shape symmetry, the structure of Fig. 1, and its difference only is on the dead bolt spare in the member of right side handle not to be set, and the pulling force of its spring is littler than the pulling force of left-side member medi-spring 5.If need backrest when the cushion direction turns down, as shown in Figure 3, upwards move handle 4 (seat can be provided with the one handle limiting stopper on the connecting plate 2, and is not shown among Fig. 1, handle 4 played position-limiting action when up), dead bolt spare 3 rotates, the prominent pawl of dead bolt spare 3 breaks away from the control to backrest connecting plate 1, although the prominent pawl of the dead bolt spare in the member of right side still is stuck in the notch of corresponding backrest connecting plate, this moment is owing to apply external force, the spring tension of adding in the member of right side is less, still can easily whole backrest be turned down.

What should emphasize is, this is later-model to have focused on considering being connected of seat connecting plate and car body, and in left and right two pairs of transoms lockout mechanism is set all.
