Abstract
The invention discloses a seat cushion frame of a backrest chair for a motor vehicle. The seat cushion frame has the advantages that the strength of a portion, provided with a backward-tilting device, in the seat cushion frame, can be guaranteed while cost can be reduced. An inward flange (10) is arranged at the back end of the portion, provided with the backward tilting device (3), in the seat cushion frame (1), and a reinforced flange (11) extending backwards is arranged at the front end of the inward flange (10) .
Description
Technical field
The present invention relates to install the seat frame of the automobile-use chair (リ Network ラ イ ニ Application グ シ one ト) of layback device (リ Network ラ イ ニ Application グ デ バ イ ス) in rear end side.
Background technology
Chair is in the past gone up by the layback device at the fore-and-aft direction Connection Block chair back (back-rest) freely that fascinates at seat cushion (seat portion), goes up the stationary member of installation seat safety strap at the seat frame (seat portion framework) of this seat cushion.Big load when behind the back of seat effect self-propelled vehicle of this chair, hitting etc. then around the hinge of the layback device of this load concentration in above-mentioned seat frame, exist the seat frame distortion of this part or the danger of be full of cracks.
For this reason, the above-mentioned distortion of seat frame etc. is partly welded, or increase thickness of slab, thus strengthened rigidity.
For this reason, cause the increase of weight, the increase of cost etc., undesirable.
In addition, the part of the parts of formation layback device etc. is exposed to the outside of seat frame, so, the resinous lid that covers it is installed on the seat frame.For this reason, need to cover the otch that usefulness is installed and be located on the seat frame, the problem that exists this otch that the rigidity of seat frame is descended.
Summary of the invention
Therefore, the objective of the invention is to guarantee the rigidity of the part of the installation layback device in the seat frame, and realize lightweight, in addition, prevent that above-mentioned lid from installing the otch of usefulness and causing the rigidity of seat frame to descend.
In order to reach above purpose, this first invention provides a kind of framework structure of automobile-use chair, this automobile-use seat at the rear portion of the seat frame of seat cushion through the back rest of layback device with the mode mount pad chair back that can fascinate at fore-and-aft direction; Wherein: in the rear end of above-mentioned seat frame square warpage is set inwardly and the inward flange that forms, is provided with at the front end of this inward flange and extends the reinforcement flange that is provided with towards the rear.
This second invention is provided with on above-mentioned reinforcement flange and is used for the installation portion of mounting cover.
According to this first invention, by inward flange and the rear end that is connected the reinforcement flange reinforced seat poppet of this inward flange.For this reason, though when hitting behind the vehicle etc. in the big load of back of seat effect, load also is input to the rear end of seat frame through the layback device, do not produce distortion in the rear end of seat frame, chap.
Therefore, do not need as above-mentioned in the past the welding deep framing, increase the thickness of slab of seat frame, so, can realize lightweight.
According to this second invention, can be at the installation portion mounting cover of above-mentioned reinforcement flange, so, do not need as product in the past the otch etc. that lid is installed usefulness to be set at seat frame.Therefore, can prevent that otch from causing the rigidity of seat frame to descend.

Fig. 2 is the cutaway view of Figure 1A-A line.
Fig. 3 wants the block diagram of portion for the present invention.
Fig. 4 is the block diagram that has used the automobile-use seat of framework structure of the present invention.
The specific embodiment
Embodiment
Fig. 1 representes the framework structure of automobile-use seat of the present invention, the seat frame of Reference numeral 1 expression seat cushion among the figure, and the back rest of Reference numeral 2 expression back of seats, back rest 2 is connected with the mode that can fascinate by layback device 3 with respect to seat frame 1.
Seat frame 1, back rest 2 all form with sheet metal, and be as shown in Figure 2, about the posterior medial of seat frame 1 overlap the bottom of the back rest 2 about the ground configuration, connect the bottom of back rest 2 with the mode that can rotate with S. A. 31 at the rear portion of seat frame 1.
In addition, in diagram constitutes, the seat frame 1 about being located at about back rest 2 on the above-mentioned S. A. 31 of layback device 3,3 usefulness be connected, the layback device 3 about this is through control lever 33 is operated, with latch-release.
Back rest 2 and seat frame 1 about layback device 3 is located at; This layback device 3 by lockout mechanism 30, remove S. A. 31, be fixed on control lever 33 on this S. A. 31, reach disc spring 32 etc. and constitute with the locking of above-mentioned lockout mechanism 30; This control lever 33 makes S. A. 31 rotations and removes above-mentioned locking; This disc spring 32 is at back rest 2 side hooks one end, at the seat frame 1 side hook other end, towards the place ahead to back rest 2 application of forces.Control lever 33 is installed on a side the layback device 3.
The seat frame 1 of the layback device 3 about above being provided with is like Fig. 2, shown in Figure 3, and integral body is provided with inwardly that the side is flexed into rectangular-shaped and inward flange 10 formation in the rear end of seat frame 1.In Fig. 2, Fig. 3, Reference numeral 10A representes the front side flange part of inward flange 10 among the figure.Reference numeral 15 is layback device installation portion among the figure, and title 15A representes the inserting hole of S. A. 31, the Reference numeral 15B device mounting hole of representing to swing back.
This inward flange 10 surrounds the 3 ground settings of layback device, so strengthened in the rear portion of the seat frame 1 around the layback device 3.
Front end at the inward flange 10 of the rear end side of seat frame 1 is provided with the reinforcement flange 11 that extends towards the rear integratedly, strengthens the rear end side of flange 11 further reinforced seat poppets 1 by this.The rear end side that is provided with the seat frame 1 nearby of this reinforcement flange 11 is the most concentrated part of big load when behind self-propelled vehicle, hitting, and this part is strengthened by strengthening flange 11, so be full of cracks can is not out of shape or produce to the rear end side of seat frame 1 when hitting behind the self-propelled vehicle etc.
On above reinforcement flange 11, be provided with the mounting hole 11A that is used for fixing synthetic resin cap 4, this synthetic resin cap 4 covers the part of the disc spring 32 and the control lever 33 of layback device 3.As shown in Figure 2, in this mounting hole 11A, pass and insert the mount pin 41 that leads at the mounting hole (not shown) of lid 4, thereby can the rear end of lid 4 be fixed on the seat frame 1.
Therefore, strengthen flange 11 and become the carriage that lid is installed usefulness, need carriage be set separately on seat frame 1, in addition, also do not need on seat frame, to offer as in the past the mounting hole that lid is installed usefulness.
The present invention constitutes as above, so, by strengthening around the layback device 3 that is located at inward flange 10 on the seat frame 1 and the seat frame 1 of strengthening flange 11 pairs of easy deformation, be full of cracks when having imported big load.
In addition, owing to above-mentioned inward flange 10, strengthen flange 11 and get final product through seat frame 1 being extended be provided with, so, the cost reduction.
