  However, in such a conventional child seat anchor structure, it is necessary to use a high-rigidity member such as normalized steel as the anchor member. Moreover, since the anchor member 7 is configured to be fixed to the parcel panel 4 using the bolt member 13 and the nut member 14a of the nut plate 14, the number of parts used for fastening is increased, and the weight and manufacturing are increased. There was a problem that the increase in cost could not be suppressed.

  In order to reduce the parts used for fastening, a structure in which the fixing surface portion 9 is welded to the parcel panel 4 is also conceivable. In this case, if the plate thickness of the anchor member 7 is increased, welding to the parcel panel 4 is possible. There was also a problem that became difficult.

  In particular, it is difficult to perform welding by combining three parcel reinforcements (not shown) located below the parcel panel 4 and increasing the total plate thickness.

  In addition, it is conceivable to weld the anchor member 7 and the parcel panel 4 while avoiding the parcel reinforcement. In this case, the fixing surface portion 9 is set wide to improve the mounting rigidity in the fixed state. I have to let it. However, when a peripheral member such as a speaker is present on the parcel panel 4, it interferes and it is difficult to set the fixing surface portion 9 wide.

  Furthermore, in the conventional child seat anchor structure, since the screw leg portion 12a of the bolt member 12 protrudes into the trunk room 13, there is a possibility that the luggage stored in the trunk room 13 may be damaged.

  Accordingly, an object of the present invention is to solve the above-described problems, to secure sufficient mounting rigidity without using an expensive high-rigidity member, and to produce a child seat anchor structure and an anchor member that are easy to manufacture and lightweight. It is to provide a manufacturing method.

In order to solve the above-mentioned problems, in the invention described in claim 1, in order to fix the child seat to the seat portion of the vehicle, an anchor member for locking and fixing the child anchor on the child seat side is provided on the parcel panel on the vehicle side. In the child seat anchor structure, the anchor member is formed by folding a flat plate-like member into a two-layered structure, a locking portion having a locking hole for locking and fixing the child anchor, and a bent portion extending from the locking portion. A flat plate portion provided, one of the two flat plate portions extending longer than the other, forming an insertion hole through which the locking portion is inserted on the upper surface of the parcel panel, the said plate, is welded fixed contact is allowed three to weld from the parcel panel back side contact of a single flat plate portion which is longer extended than the other, from below That a reinforcement, said by welded in a sandwich with three by welding between the parcel panel, as characterized child seat anchor structure to be welded fixing the child anchor in two places in the longitudinal direction of the vehicle body with respect to the parcel panel Yes.

  According to the first aspect of the present invention configured as described above, since the locking portion in which the locking hole is formed is formed by folding the flat plate member into two sheets, an expensive high-rigidity member is used. Even if it is not, sufficient mounting rigidity can be secured.

  Since the flat plate portion is contacted from the back side of the parcel panel and fixed by welding, the load from the child anchor locked in the locking hole presses the flat plate portion toward the back side of the parcel panel. To do. For this reason, the mounting rigidity can be easily improved as compared with the case where a load acts in the peeling direction.

  Moreover, unlike conventional cases, fastening members such as bolt members are not provided in the trunk room, and the possibility of damaging the luggage stored in the trunk room is reduced.

  In addition, since the number of parts is reduced as compared with the prior art, an increase in weight and manufacturing cost is suppressed.

  Moreover, since the flat plate part comprised from one flat plate member is contact | abutted and fixed by welding from the said parcel panel back surface side, the increase in a weight is further suppressed.

  Furthermore, since the flat plate portion is in contact with the back surface side of the parcel panel, for example, even when a peripheral member such as a speaker is present on the top surface side of the parcel panel, welding can be performed with a relatively large area. .

  In addition, the structure described in claim 2 is characterized by the child seat anchor structure according to claim 1, wherein the folding direction is obtained by combining the punching direction of the flat plate member.

  In the structure according to claim 2, the anchor member is formed by folding the flat plate-shaped member so that the so-called burrs are located on the inner side and finished. Even if the process is simplified, a good quality anchor member can be obtained.

  In addition, since the flat plate portion is sandwiched between the reinforcement upper surface portion abutted from below and the parcel panel lower surface to form three sheets, the mounting rigidity of the mounting portion is further improved.

  According to a third aspect of the present invention, when the flat member is punched, the anchor member is punched in advance in the portion serving as the locking hole, and the burr direction formed by the punching is defined as the inner side. A method for manufacturing an anchor member used in the child seat anchor structure according to claim 1 or 2 is formed by folding and stacking two sheets.

  According to the third aspect of the present invention, the so-called burrs formed when the flat plate member is punched are located inside the anchor member that is folded and overlapped so that the finishing process is simplified. Can be

  Next, the operation of the first embodiment will be described along the manufacturing process of the anchor member 17.

  In the anchor member 17 according to the first embodiment, when the flat plate member is punched, a pair of the portions serving as the locking holes 19 and 19 are punched with a predetermined distance therebetween. And the burr | direction direction formed by this punching process is folded as an inner side, and the said latching | locking part 20 and a part of said flat plate part 21 are made into two sheets.

  At this time, the locking holes 19 and 19 are overlapped to form one locking hole 19 of the locking portion 20. Further, bending between the kick-up portion 18 and the flat plate portion 21 is also formed during the folding.

  In this way, so-called burrs formed when the flat plate member is punched are positioned inside the anchor member 17 that is folded and overlapped, so that the finishing process can be simplified.

  Next, a process of welding and fixing the anchor member 17 to the rear parcel shelf 16 will be described.

  The kick-up portion 18 of the anchor member 17 is inserted into the insertion hole 23 from the lower side to the upper side, and the flat plate portion 21 of the anchor member 17 is brought into contact with the lower surface side of the rear parcel shelf 16.

  In this state, the extended portion 18a and the flat plate portion 21 are punched and fixed by welding at two locations on the left and right sides together with the periphery of the insertion hole 23.

  Further, the flat plate portion 21 is sandwiched between the upper flange portion 24a of the reinforcement 24 abutted from below and the lower surface of the rear parcel shelf 16, and is punched at three locations and fixed by welding. The

  As described above, the flat plate portion 21 is sandwiched between the upper flange portion 24a of the reinforcement 24 abutted from below and the lower surface of the rear parcel shelf 16, and is formed into three pieces. The mounting rigidity of the mounting portion of the member 17 is further improved.

  Further, in the child seat anchor structure of the first embodiment, the locking portion 20 in which the locking hole 19 is formed is formed by folding a flat plate-like member into two sheets, so that an expensive high-rigidity member Sufficient mounting rigidity can be ensured without using.

  Further, since the flat plate portion 21 is contacted from the lower surface side of the rear parcel shelf 16 and is fixed by welding, a load in the pulling direction from the child anchor 6 locked in the locking hole 19 is applied to the locking hole 19. It acts to press the flat plate portion 21 toward the lower surface side of the rear parcel shelf 16.

  For this reason, the mounting rigidity can be easily improved as compared with the case where a load acts in the peeling direction.

  In addition, since the anchor member 17 is fixed by welding, a fastening member such as a bolt member is not projected in the trunk room 13 as in the prior art. The risk of damage is reduced.

  Moreover, since the number of parts of fastening members, such as a bolt member, reduces compared with the past, the increase in a weight and manufacturing cost is suppressed.

  And in this Embodiment 1, since the flat plate part 21 comprised from one board | plate material is contact | abutted from the lower surface side of the said rear parcel shelf 16, and is fixed by welding, all the flat plate parts 21 are comprised by 2 sheets. Further, the increase in weight is suppressed as compared with that to be done.
