As Fig. 3～shown in Figure 5, handle arrangement for release 10 is made of Handleset 15.This Handleset 15 for example be assemblied in the luggage compartment wall portion that forms the left side rear lateral portion interior plate 11b board and cover between the ornamental trimming part of ornamental trimming 12b in this rear lateral portion interior plate 11b fwd.Certainly, Handleset 15 is assemblied in the place near peristome 8.

Structure to Handleset 15 describes.As shown in Figure 5, for example, in this assembly 15, adopt handle component 20 assembling and Componentized structures with plastic base component 16 and plastic latch-release operation usefulness.Specifically, the rectangular frame shape of base component 16 configuration examples as extending along the vehicle body fore-and-aft direction.The part of the both sides of the length direction of the opening of base component 16, respectively by the wall portion 17 that comprises through hole 17a, comprise that the wall portion 18 of through hole 18a blocks.And, wall portion 17 parts are used base as ornamental trimming assembling, wall portion 18 parts are fixedly used base as assembly.And, the tab that 19 expressions are given prominence to side direction from wall portion 18 (forming ornamental trimming assembling base).And as shown in Figure 3, ornamental trimming assembling base, tab 19 are locked in the therefrom outstanding various boss portion 13 in the inside of ornamental trimming 12b.

As Fig. 3～shown in Figure 5, handle component 20 comprise the shaped as frame handle portion 21 of the opening front face side (luggage compartment 6 sides) that is disposed at base component 16 and from the vehicle body rear of this handle portion 21 to the outstanding arm 22 in the oblique rear of the inside mediad of the frame part of side.Wherein, the root of arm 22 is supported by a pair of projection piece 16a that the edge of opening from base component 16 erects by pin parts 23 free to rotately, and handle component 20 can be rotated at the vehicle body fore-and-aft direction.

25a is divided in the bottom that the handle portion 21 of this handle component 20 runs through the part 25 that caves in, and is disposed at recess, and wherein, depression parts 25 are used for operating the handle of a part of plate face of embedding ornamental trimming 12b.Specifically, the frame part 21a～21c of three directions of the vehicle body rear side of handle portion 21 is along the edge of opening configuration of three directions of the vehicle body rear side of recess, and the frame part 21d in remaining vehicle body the place ahead is configured to from the centre across the opening of recess.And, make handle portion 21 integral body towards luggage compartment 6.According to this structure, just can mention the frame part 21d of handle portion 21 with the recess finger partly in the place ahead of inserting frame part 21d.That is, become and to carry out lever operated structure.And 26 expressions are used to make handle portion 21 or arm 22 to connect and divide the breakthrough part of the part formation of 25a in the bottom.

And, locking/latch-release the portion 5 of the top ends of arm 22 and above-mentioned (backrest) incidence regulating mechanism 4 is connected by the cable parts 27 of operation usefulness, wherein, the cable parts 27 of this operation usefulness connect up at the inboard of rear lateral portion ornamental trimming 12, the underfloor of luggage compartment 6.Therefore, shown in the two point dotted line among Fig. 1,, then remove the locking that keeps each back of seat 3b posture if lift operation handlebar hand 21 (direction that it is erected).

On the other hand, as Fig. 3～shown in Figure 5, the assembly of base component 16 is fixing to divide 25a to be fixed on pedestal on by connection structure 30 (anchor fitting) with the bottom of the recess directly over it with base, for example on the support 31 of sheet metal system, wherein, this pedestal is positioned at the junction surface of rear lateral portion interior plate 11b and brace panel 11c.By this connection structure 30, Handleset 15 is fixed on wall portion 11, promptly on the body panels.In this connection structure 30, adopt such structure: when the rear portion at vehicle body 1 applies impulsive force more than or equal to specified value, make base component 16 stay in the ornamental trimming 12b structure that goes up, come off from support 31 (body panels side) simultaneously.

In this connection structure 30, used Fig. 3 for example～shown in Figure 5 be pre-assembled on the support 31 grommet 33 and with the structure of the bail 35 of these grommet 33 combinations.Specifically, grommet 33 comprises that an end is formed with the cylindrical portion 33b of flange part 33a.And grommet 33 also comprises narrow 33c (forming the part of engaging support) at the inner peripheral surface of the other end.This grommet 33 is inserted in the grommet mounting hole 31a of support 31 formation from the ornamental trimming side.Like this, grommet 33 is installed on the support 31 towards the posture of the plate face of rear lateral portion interior plate 11b towards cosmetic side, its tip side with the bottom side (entrance side) that comprises flange 33a.

As Fig. 3～shown in Figure 5, bail 35 comprises necking part 35a at the outer peripheral face of tip side, comprises discoid card-tight part 35b at base end part.The top ends of this bail 35 from luggage compartment 6 run through through hole 25c (with reference to the diagram of Fig. 5), with the overlapping through hole 18a (base component 16) of this through hole 25c, insert the grommet 33 on the support 31, wherein, this through hole 25c divides on the recess 25b of 25a in the bottom of recess.And the necking part 35a of bail 35 engages with the narrow 33c of grommet 33, and base component 16, depression part 25 and middle ornamental trimming 12b are fixed in the wall portion 11.And, bail 35 and grommet 33 regulation for example when shear direction applies the load of about 15N, engage under the fastening state that bail 35 comes off from grommet 33.According to this engaging situation, if apply the impulsive force that can make 11 distortion of wall portion, then be accompanied by the relative displacement of wall portion 11 and rear lateral portion ornamental trimming 12 from body tail, bail 35 is deviate from from grommet 33.The action that utilizes this bail 35 to come off makes Handleset 15 (base component 16, handle component 20) along with middle ornamental trimming 12b (above staying) comes off from wall portion 11.

That is, be example during with rear impact shown in Figure 7, the action that comes off of Handleset 15 is described.Each state of Handleset 15 when Fig. 7 (a) illustrates locking back of seat 3b, 3b posture.

Here, suppose that vehicle body 1 is collided.At this moment the impulsive force F that applies from body tail is delivered on grommet 33 and the bail 35 through wall portion 11.Thus, impulsive force F applies effect from shear direction to bail.

At this moment, suppose that impulsive force F is the load that can make wall portion 11 distortion of luggage compartment 6.

So at this moment, as shown in Figure 6, bail 35 is subjected to the load (approximately more than or equal to 15N) that applies from shear direction, shown in the arrow among Fig. 6, comes off from grommet 33.

Here, base component 16 is maintained on the middle ornamental trimming 12b by bail 35.And the ornamental trimming assembling of base component 16 is still being supported (during assembling Handleset 15, being assembled in the parts on the rear lateral portion ornamental trimming 12) by the boss portion 13 of middle ornamental trimming 12b with base.

Thus, during staying, the integral body of Handleset 15 (base component 16, handle component 20) on the ornamental trimming 12b, comes off from wall portion 11 simultaneously.

According to coming off of this Handleset 15, for example because impulsive force F, shown in Fig. 7 (b), even comprise Handleset 15 parts wall portion 11, be that the wall portion 11 of the open circumferential of luggage compartment 6 is deformed into to the inside and pours into, perhaps, the fastener of ornamental trimming 12b comes off in the prevention, and the handle component 20 of Handleset 15 can not be pushed up at the edge part of the breakthrough part 26 that handle component 20 is connected yet.That is, shown in Fig. 7 (b), handle component 20 still keeps the lock-out state of originally locking back of seat 3b, 3b, the state of the handle bar that promptly falls down.

Therefore, even apply the impulsive force F of wall portion 11 distortion that can make luggage compartment 6 from body tail, the handle component 20 of Handleset 15 yet can and not operated accidentally and remove side by the distortion of wall portion 11 towing.

Therefore, remove the locking of back of seat 3b, 3b in the time of can preventing vehicle collision accidentally, thereby improve safety.

Especially Handleset 15 is being stayed in the structure of cosmetic side, owing to used the embedded structure of grommet 33 and bail 35, thus not only simple, and cost is also low.

In addition, the present invention is not limited to the foregoing description, and it is whole or local remote servicing also all belongs to object of the present invention to carry out seat, also can carry out various changes and enforcement in aim scope of the present invention.
