It has a seat unit 30 and. Further, the child seat 10 has a pair of fixing units 100 extending rearward from the back surface of the cradle 20. The pedestal 20 is fixed to the seat 1 of the vehicle by connecting the fixing unit 100 to a fixture (for example, a latch corresponding to the ISOFIX method) provided on the seat 1 of the vehicle (for example, a latch corresponding to the ISOFIX method). Further, the child seat 10 has a support leg 110 extending from the pedestal 20 of the child seat main body 11. As shown in FIG. 1, the support leg 110 extends to the floor surface 3 of the vehicle that supports the seat 1 of the vehicle, and supports the front portion of the child seat body 11 (cradle 20) from below.

In the present specification, the terms "upper", "lower", "front" and "rear" for the child seat 10 and its respective parts are referred to as "upper" based on the normal running of the vehicle unless otherwise specified. , "Bottom," "before," and "after."

Hereinafter, each part of the child seat main body 11 will be described in more detail with reference to FIGS. 1 to 5. FIG. 3 is a perspective view of the pedestal 20, and FIG. 4 shows the bottom member 22 of the pedestal 20, the fixing unit 100, the support leg 110, the shaft 33 connecting the seat unit 30 and the pedestal 20, and the pedestal 20. It is a perspective view which shows together with the engaging shaft 34 of a seat unit 30. Further, FIG. 5 is a perspective view showing the bottom side of the seat unit 30.

First, the cradle 20 will be described with reference to FIGS. 1 to 4. As shown in FIGS. 3 and 4, the pedestal 20 includes a pair of connection frames 21 and 21 to which the seat unit 30 is connected, a bottom member 22 and a cover member 23 that accommodate the pair of connection frames 21 and 21. Have.

Both ends of a shaft 33, which will be described later, held by the seat unit 30 are connected to the pair of connection frames 21 and 21 so as to be movable in the front-rear direction. Specifically, the pair of connecting frames 21 and 21 are provided with holes 21h into which the shaft 33 extending in the width direction of the pedestal 20 is inserted. In the illustrated example, the hole 21h is an elongated hole having a longitudinal direction in the front-rear direction of the cradle 20. As the shaft 33 moves in the elongated hole 21h along its longitudinal direction, the seat unit 30 can move in the front-rear direction on the pedestal 20.

As shown in FIG. 1, the bottom member 22 faces the base portion 22a arranged on the seat surface 1a of the vehicle seat 1 and the back portion 1b of the vehicle seat 1 extending upward from the rear end portion of the base portion 22a. It has a rising portion 22b and the like. As is well shown in FIG. 4, the base portion 22a of the bottom member 22 holds the pair of fixing units 100 at both ends in the width direction thereof. Further, a support leg 110 is connected to the front end portion of the base portion 22a. The base 22a supports the seat unit 30 from below. In other words, the seat unit 30 slides on the upper surface 24 of the base 22a.

The portion 24s of the upper surface 24 of the base portion 22a of the bottom member 22 with which the seat unit 30 is in sliding contact is curved, and the seat unit 30 is tilted rearward as it moves forward. As a result, the seat unit 30 reclines on the pedestal 20 as it moves forward on the base 22a (see FIG. 2).

Further, on the upper surface 24 of the base portion 22a, a regulation portion 25 for restricting the movement of the seat unit 30 with respect to the pedestal 20 in the front-rear direction is formed. The regulating portion 25 is provided at the center of the bottom member 22 in the width direction. The regulating portion 25 includes a pair of ridge portions 26, 26 extending in the front-rear direction and separated from each other in the width direction. Each of the ridges 26 and 26 is provided with a groove 26g that can receive the engaging shaft 34 of the seat unit 30 described later from above. A plurality of grooves 26g are provided so as to be separated from each other in the front-rear direction of the bottom member 20. Thereby, the position of the seat unit 30 with respect to the pedestal 20 in the front-rear direction can be adjusted, and the reclining angle of the seat unit 30 with respect to the pedestal 20 can be adjusted.

As shown in FIG. 3, the cover member 23 has a base cover portion 23a that covers the base portion 22a of the bottom member 22 from above, and a rising top cover portion 23b that covers the rising portion 22b from the front. An opening 23h for exposing the regulation portion 25 is provided in the center of the base cover portion 23a. Through this opening 23h, the ridges 26, 26 of the regulating portion 25 engage with the engaging shaft 34 of the seat unit 30.

Next, the seat unit 30 will be described. As shown in FIG. 1, the seat unit 30 has a base 31 supported by a cradle 20 and a seat 40 connected to the base 31.

As is well shown in FIG. 5, a pair of rail members 32, 32 sliding on the bottom member 22 of the pedestal 20 are provided below the base 31. The rail members 32 and 32 hold the shaft 33 that connects the base 31 and the cradle 20.

Here, the connection frames 21 and 21 described above are provided on both outer sides of the pair of rail members 32 and 32 in the width direction. Further, as shown in FIG. 5, the pair of rail members 32, 32 hold an intermediate portion of the shaft 33 extending in the width direction of the base 31. Then, as shown in FIG. 4, both ends of the shaft 33 are inserted into the elongated holes 21h provided in each of the pair of connecting frames 21 and 21. In this way, the seat unit 30 is connected to the cradle 20.

The base 31 further has an engaging shaft 34 extending in the width direction of the base 31 in front of the shaft 33 and between the rail members 32, 32. The engaging shaft 34 engages with the ridges 26, 26 of the pedestal 20. Specifically, as shown in FIG. 4, the engaging shaft 34 is housed in the grooves 26g of the ridges 26, 26. As a result, the movement of the base 31 in the front-rear direction with respect to the pedestal 20 is restricted. By operating the operating means 35 provided on the base 31, the engaging shaft 34 moves upward with respect to the rail members 32 and 32 and comes out of the grooves 26g of the ridges 26 and 26. When the engaging shaft 34 comes out of the groove 26g of the ridges 26, 26, the engagement between the engaging shaft 34 and the ridges 26, 26 is released, and the base 31 moves in the front-rear direction with respect to the pedestal 20. You can move to. The engaging shaft 34 is urged by an urging means (not shown), and moves downward when the operation of the operating means 35 is stopped.

Next, the fixed unit 100 will be described. As shown in FIG. 4, the fixing unit 100 is attached to and detached from a square pillar (cylinder) -shaped metal frame 101 extending in the front-rear direction of the cradle 20 and a fixture provided at the rear end of the metal frame 101 and seat 1 of the vehicle. It has a possible connector 102 and. The fixing unit 100 is further provided at the front end of the metal frame 101, and has a releasing operation unit 103 for releasing the connection between the connecting tool 102 and the fixing tool of the seat 1 of the vehicle. The fixed unit 100 is configured to have a variable length in order to ensure versatility for the vehicle.

Next, the support leg 110 will be described. As shown in FIG. 1, the support leg 110 extends to the floor surface 3 of the vehicle. As a result, the support leg 110 supports the front end portion of the bottom member 22 arranged on the seat surface 1a of the seat 1 of the vehicle from the floor surface 3. The support leg 110 is also configured to have a variable length in order to ensure versatility for the vehicle.

By the way, in general, when the vehicle suddenly decelerates due to a strong impact from the front, the seat unit in which the inertial force acts in the front continues to be properly connected to the pedestal (that is, the seat unit is the pedestal). The connection frame to which the seat unit is connected is made of a special high-strength metal plank so that it will not fall out of the seat unit. Alternatively, the strength of the connecting frame is improved by welding it to surrounding parts.

However, the connection frame made of a special metal plate has been a factor in increasing the weight of the child seat and increasing the product cost. Welding the connecting frame to the surrounding parts also complicates the assembly of the child seat.

In consideration of such circumstances, the child seat 10 of the present invention has been devised to reduce the weight of the child seat 10, reduce the product cost, and simplify the assembly.

Specifically, as shown in FIGS. 6 and 7, each connection frame 21 includes a resin frame 50 made of a resin such as polypropylene and a bent sheet metal 51 fixed to the resin frame 50. By forming a part of the connection frame 21 with resin, the weight of the connection frame 21 can be reduced. Further, by fixing the sheet metal to the resin frame 50, the resin frame 50 can be reinforced and the strength of the connection frame 21 can be made strong enough to appropriately connect the seat unit 30. The bent sheet metal 51 may be formed of a widely distributed sheet metal (for example, a sheet metal made of steel having a tensile strength of 270 MPa or more such as SPCC or SPHC). As a result, the connection frame 21 can be manufactured at low cost. Of course, the bent sheet metal 51 may be formed of a sheet metal made of steel such as SAPH440, which has a stronger tensile strength.

In the illustrated example, the resin frame 50 is provided on the upper surface of the metal frame 101 of the fixing unit 100. The bent sheet metal 51 is bent along both side surfaces and the bottom surface of the metal frame 101 of the fixing unit 100, and both ends thereof are fixed to both side surfaces of the resin frame 50. Thereby, the movement of the resin frame 50 and the bent sheet metal 51 with respect to the fixing unit 100 in the vertical direction and the width direction can be effectively prevented. Therefore, the stress from the seat unit 30 on which the forward inertial force acts is applied to the connection frame 21, and the connection frame 21 moves in the vertical direction or the width direction with respect to the bottom member 22 and the cover member 23 of the pedestal 20. Is effectively prevented. The movement of the resin frame 50 and the bent sheet metal 51 with respect to the metal frame 101 in the front-rear direction is regulated by a fixing mechanism (not shown) provided on the resin frame 50 and the metal frame 101.

Here, the bent sheet metal 51 is manufactured by bending the sheet metal along both side surfaces and the bottom surface of the fixing unit 100. In other words, the bent sheet metal 51 can be manufactured only by bending the sheet metal at several places (two places in the illustrated example). Such a bent sheet metal 51 can be easily manufactured. This leads to a reduction in the manufacturing cost of the child seat 10 and a simplification of the manufacturing process. Further, the bent sheet metal 51 is fixed to the resin frame 50 by fasteners such as bolts. This simplifies the mounting of the connecting frame 21 as compared to welding mounting.

The bent sheet metal 51 does not have to cover all of both side surfaces of the resin frame 50. In the illustrated example, the bent sheet metal 51 covers only a part of each side surface of the resin frame 50. As a result, the bent sheet metal 51 can be miniaturized and manufactured at a lower cost.

In the illustrated example, as can be seen from FIGS. 6 and 7, the area of each resin frame 50 covered by the sheet metal 51 bent from the inside in the width direction of the pedestal 20 is bent from the outside in the width direction. It is larger than the area of each resin frame 50 covered by the sheet metal 51. Here, when a forward inertial force acts on the seat unit 30, the inner portion of each resin frame 50 in the width direction is a shaft 33 connecting the seat unit 30 and the pedestal 20 as compared with the outer portion thereof. Because of the greater stress. Therefore, by making the area where the inner portion is covered by the bending sheet metal 51 larger than the area where the outer portion is covered by the bending sheet metal 51, the resin frame 50 can be effectively used by the miniaturized bending sheet metal 51. Can be reinforced.

Further, the bent sheet metal 51 does not have to cover all the side portions of the portions where the resin frame 50 and the fixing unit 100 come into contact with each other. In the illustrated example, the bent sheet metal 51 covers a part of the side portion of the portion in contact with each other. The length of the contact surface of the resin frame 50 in contact with the fixing unit 100 in the front-rear direction is longer than the length of the bent sheet metal 51 on the side of the contact surface in the front-rear direction.

Each of the pair of resin frames 50 is provided with the above-mentioned elongated hole 21h into which the end portion of the shaft 33 is inserted. In the illustrated example, an elongated hole 51h through which the end portion of the shaft 33 passes is further provided at a position facing the elongated hole 21h of the resin frame 50 of the bent sheet metal 51. The periphery of the edge of the elongated hole 21h of the resin frame 50 is reinforced by the bent sheet metal 51. The edge of the elongated hole 21h of the resin frame 50 is a portion that receives stress from the shaft 33 that connects the seat unit 30 and the pedestal 20 when a forward inertial force acts on the seat unit 30. By reinforcing such a portion with the bent sheet metal 51, there is an effective possibility that the edge portion of the elongated hole 21h of the resin frame 50 is deformed by the stress from the shaft 33 and the shaft 33 comes out of the elongated hole 21h. It can be reduced.

In the illustrated example, the resin frame 50 is rib-reinforced. Thereby, the strength of the resin frame 50 itself can be improved. As is well shown in FIG. 8, some of the ribs 52a of the ribs 52 of the resin frame 50 extend in a direction orthogonal to the longitudinal direction of the elongated holes 21h of the resin frame 50. Here, when a forward inertial force acts on the seat unit 30, the direction of stress acting on the edge of the elongated hole 21h of the resin frame 50 from the shaft 33 connecting the seat unit 30 and the pedestal 20 is generally described above. It is along a direction orthogonal to the longitudinal direction of the elongated hole 21h. That is, the direction of the stress is along the extending direction of some of the ribs 52a. Generally, when the stress applied to the rib is along the extending direction of the rib, the rib does not bend easily. Therefore, the edge portion of the elongated hole 21h can be effectively reinforced by the partial rib 52a.

Further, in the illustrated example, the resin frame 50 has an upward extending portion 50a extending upward at the rear end portion. When the resin frame 50 has such an upward extending portion 50a, it is possible to prevent the connecting frame 21 which has been stressed rearward from the shaft 33 connecting the seat unit 30 and the pedestal 20 from tilting backward. be able to. For example, when the vehicle suddenly stops and a force is applied to the seat unit 30 to bounce backward, the upward extending portion 50a of the resin frame 50 is the rising portion 22b of the cradle 20 and / or the back of the seat 1 of the vehicle. By being supported from the rear by 1b, the seat unit 30 is prevented from falling backward. In the illustrated example, the upward extending portion 50a extends between the rising portion 22b of the bottom member 22 and the rising portion cover portion 23b of the cover member 23.

In the above-described example, the example in which the seat unit 30 holds the shaft 33 and the connecting frame 21 is provided with the elongated hole 21h into which the shaft 33 is inserted has been described, but the present invention is not limited to this. The resin frame 50 of the cradle 20 may hold the shaft 33, and the seat unit 30 may be provided with an elongated hole 21h into which the end portion of the shaft 33 is inserted.

As described above, according to the present embodiment, the child seat 10 attached to the seat 1 of the vehicle and used is the pedestal 20 and the pedestal 20 arranged on the seat surface 1a of the seat 1 of the vehicle. It includes a seat unit 30 that is supported, and a fixed unit 100 that is held by the pedestal 20 and extends rearward from the pedestal 20 to fix the pedestal 20 to the seat 1 of the vehicle. The cradle 20 includes a resin frame 50 provided on the upper surface of the fixing unit 100, and a bent sheet metal 51 bent along both side surfaces and the bottom surface of the fixing unit 100 and fixed to the resin frame 50. doing. Then, one of the resin frame 50 and the seat unit of the pedestal 20 holds the shaft 33 inserted into the hole 21h provided in the other of the resin frame 50 and the seat unit 30 of the pedestal 20.

According to such a child seat 10, since the resin frame 50 is included in a part of the connecting member 21 to which the shaft 33 is connected, the weight of the connecting member 21 (and therefore the child seat 10) can be reduced. Further, since the bent sheet metal 51 is fixed to the resin frame 50 to reinforce the resin frame 50, it is sufficient to appropriately connect the strength of the connecting member 21 to the shaft 33 connected to the seat unit 30. Can be strong. The bent sheet metal 51 may be formed of a sheet metal that is widely and generally distributed. As a result, the connecting member 21 can be manufactured at low cost.

In the present embodiment, the seat unit 30 has a pair of rail members 32, 32 that slide on the pedestal 20. Further, the pair of resin frames 50, 50 are provided on both outer sides of the pair of rail members 32, 32 in the width direction. Then, the intermediate portion of the shaft 33 is held by the seat unit 30, and both end portions of the shaft 33 are inserted into holes 21h provided in each of the pair of resin frames 50. As a result, the seat unit 30 and the cradle 20 can be connected with a small number of parts.

In the present embodiment, the bent sheet metal 51 is provided with a hole 51h through which the shaft 33 passes at a position facing the hole 21h of the resin frame 50. As a result, the edge of the hole 21h of the resin frame 50 is reinforced by the bent sheet metal 51.

In the present embodiment, the resin frame 50 is rib-reinforced. As a result, the strength of the resin frame 50 itself is improved.

In the present embodiment, the resin frame 50 is provided with a hole 21h into which the shaft 33 is inserted, the hole 21h has a longitudinal direction, and the rib 52a is orthogonal to the longitudinal direction of the hole 21h of the resin frame 50. Is extended. As a result, the edge portion of the hole 21h of the resin frame 50 can be effectively reinforced.

In the present embodiment, the area of each resin frame 50 covered by the bent sheet metal 51 from the inside in the width direction is larger than the area of each resin frame 50 covered by the bent sheet metal 51 from the outside in the width direction. As a result, the resin frame 50 can be effectively reinforced while the bent sheet metal 51 can be miniaturized and manufactured at low cost.

In the present embodiment, the length of the contact surface of the resin frame 50 in contact with the fixing unit 100 in the front-rear direction is longer than the length in the front-rear direction of the bent sheet metal 51. As a result, the bent sheet metal 51 can be miniaturized and manufactured at low cost.

In the present embodiment, the holes 21h provided on the other side of the resin frame 50 and the seat unit 30 have a longitudinal direction, and the shaft 33 is oriented in the longitudinal direction of the holes 21h provided on the other side of the resin frame 50 and the seat unit 30. By moving along, the seat unit 30 reclines on the cradle 20.

In the present embodiment, the rear end portion of the resin frame 50 has an upward extending portion 50a extending upward. As a result, it is possible to prevent the resin frame 50, which has been stressed rearward from the shaft 33 of the seat unit 30, from falling backward.

In this embodiment, the resin frame 50 is made of polypropylene.

Although some modifications to the above-described embodiments have been described above, it is naturally possible to apply a plurality of modifications in combination as appropriate.
