The vehicle seat 1 shown in fig. 1 (hereinafter also simply referred to as a seat 1) includes a seat cushion 2, a seatback 3, a headrest 4, a seatback frame 5, and a fastening bracket 7. The seat cushion 2 is a portion for supporting the buttocks of the seated user. The seat back 3 is a portion for supporting the back of the seated user. The headrest 4 is a portion for supporting the head of a seated user. Further, "occupant" refers to an occupant of the vehicle or a person using a seat for the vehicle.
The seat 1 of the present embodiment is used as a rear seat of a passenger car. As shown in fig. 1, the rear portion of the seat 1 is provided with a sheet metal 8 as a part of the vehicle body. Further, the directions in the following description and the drawings represent directions in a state where the seat 1 is mounted in a vehicle (i.e., a passenger car). In the present embodiment, the seat width direction coincides with the left-right direction of the vehicle, and the seat front coincides with the front of the vehicle.
< seat back and back frame >
As shown in fig. 1, a back frame 5 is provided inside the seat back 3. The back frame 5 supports the seat back 3.
< headrest >
The headrest 4 has a headrest body 41 and a headrest stay 42. The headrest body 41 is a portion that contacts the head of the occupant and directly supports the head. The headrest stay 42 supports the headrest body 41 and is attached to the headrest support portion 6, wherein the headrest support portion 6 is a support portion for supporting the headrest 4, which is provided in the back frame 5. That is, the headrest 4 is connected to the back frame 5 through the headrest stay 42 and the headrest support portion 6.
The headrest stay 42 is made of a metal pipe. In the present embodiment, two headrest posts 42 are provided (however, only one is shown in fig. 1). In a state where the headrest 4 is attached to the seat back 3, the two headrest posts 42 are separated from each other in the seat width direction (left-right direction).
< support frame >
In the present embodiment, the headrest support portion 6 for supporting the headrest 4 can be understood as the support bracket 6. As shown in fig. 2 and 3, the support bracket 6 is formed to be hollow in the inside so that the headrest stay 42 can be inserted and removed inside the support bracket 6. As an example, the support frame 6 includes a 1 st support 61 and a 2 nd support 62, and each of the 1 st support 61 and the 2 nd support 62 is a tubular metal material having a square tubular shape. The 1 st bracket 61 and the 2 nd bracket 62 correspond to the positions of the two headrest posts 43, respectively, and the 1 st bracket 61 and the 2 nd bracket 62 are fixed to an upper frame (not shown) in the back frame 5 at positions separated from each other in the seat width direction.
Further, the inner side surfaces in the seat width direction of each of the 1 st bracket 61 and the 2 nd bracket 62 are provided with a cut-and-raised portion 63 (refer to fig. 2, although only the cut-and-raised portion 63 in the 1 st bracket 61 is shown in fig. 2). When the 1 st bracket 61 and the 2 nd bracket 62 are welded to the fastening bracket 7 described later, respectively, the cut-up portion 63 serves as a locking portion for temporarily fixing the 1 st bracket 61 and the fastening bracket 7, and the 2 nd bracket 62 and the fastening bracket 7.
< fastening bracket >
The structure of the fastening bracket 7 will be described with reference to fig. 4A and 4B. The fastening bracket 7 is a plate-shaped metal member that connects the support bracket 6 (i.e., the 1 st bracket 61 and the 2 nd bracket 62) and the sheet metal 8.
As shown in fig. 4A, the fastening bracket 7 includes a base 71, and wall portions 72R, 72L extending upward from the base 71 at both ends in the seat width direction of the base 71. The wall portions 72R, 72L are provided with amplifying portions 721R, 721L, respectively, and the amplifying portions 721R, 721L protrude from the wall portions 72R, 72L in a mountain shape. The amplification parts 721R, 721L are parts that are engaged with the cut-and-raised parts 63 of the 1 st bracket 61 and the 2 nd bracket 62, respectively, when the fastening bracket 7 is welded to the 1 st bracket 61 and the 2 nd bracket 62, respectively.
In the present embodiment, the base portion 71 includes a slope portion 73 that slopes upward toward the seat rear, and a planar portion 74 that is formed continuously with the slope portion 73. The planar portion 74 is a portion connected to the main body of the vehicle. In the present embodiment, by providing the inclined surface portion 73 inclined upward, the mounting work of the fastening bracket 7 to the sheet metal 8 can be performed at a high position, thereby improving the convenience of work. However, the slope portion 73 may be inclined downward as going toward the rear of the seat according to the position of the main body portion of the vehicle to which it is actually connected. Further, the slope 73 may not be provided, and the entire base 71 may be substantially parallel to the floor surface of the vehicle.
As shown in fig. 4A and 4B, the planar portion 74 is provided with a through hole 75, and a bolt 76 (see fig. 2 and 3) to be described later is inserted through the through hole 75. As shown in fig. 4B, in order to secure workability and strength at the time of tightening the bolt 76, a portion of the planar portion 74 where the through hole 75 is provided is recessed downward as compared with its surrounding portion.
The dimensions of the fastening bracket 7 may be set according to the specifications of the support frame and the distance between the seat 1 and the sheet metal 8 that is a part of the vehicle body, and are not particularly limited. As one example, the width of the fastening bracket 7 may be formed to correspond to the interval of the 1 st bracket 61 and the 2 nd bracket 62 in the seat width direction. In order to secure the strength of the fastening bracket 7, it is preferable that the shorter the entire length (the length in the seat front-rear direction) of the fastening bracket 7 is, the better.
< support frame, fastening bracket, and method for connecting vehicle body >
A method of connecting the support bracket 6, the fastening bracket 7, and the sheet metal 8 as a part of the vehicle body will be described with reference to fig. 3.
In the present embodiment, first, the amplifying portions 721R and 721L of the wall portions 72R and 72L of the fastening bracket 7 are respectively engaged with the cut-up portions 63 of the 1 st bracket 61 and the 2 nd bracket 62, so that the fastening bracket 7 is temporarily fixed to the support bracket 6 (in other words, the back frame 5). Next, the fastening bracket 7 is fixed to the support bracket 6 by welding the temporarily fixed portion (the locking portion).
Then, the fastening bracket 7 is stacked on the upper side of the sheet metal 8 such that the through hole 75 of the planar portion 74 is aligned with the through hole 81 (refer to fig. 2) provided on the sheet metal 8. Thereafter, the bolts 76 are inserted through the through holes 75 and 81, and nuts 77 (see fig. 1) are screwed to the bolts 76 on the opposite side of the upper flat surface portion 74 of the sheet metal 8. Thereby, as shown in fig. 1 and 3, the support frame 6, the fastening bracket 7, and the sheet metal 8 are connected to each other.
[1-2. Effect ]
According to the embodiments described in detail above, the following effects can be obtained.
In the present embodiment, a support bracket 6 as a headrest support portion 6 and a sheet metal 8 as a part of a vehicle body are connected by a fastening bracket 7. That is, the fastening point between the seat 1 and the sheet metal 8 is also provided at the connection portion of the back frame 5 to the headrest 4, that is, the headrest support portion 6 (the support bracket 6). Thereby, the movement of the headrest 4 in the seat front-rear direction is more effectively restricted. Therefore, when the vehicle is involved in a collision from behind, the impact on the headrest 4 caused by the inertial movement of the occupant toward the rear of the seat is reduced, and whiplash of the occupant can be suppressed, thereby realizing a vehicle seat with high safety.
In the present embodiment, the support frame 6 as the headrest support portion 6 and the metal plate 8 as a part of the vehicle body are connected by the fastening bracket 7, wherein the support frame 6 is configured such that the headrest stay is detachably attached to the support frame 6 as described above. Thus, the position of the headrest 4 in the seat up-down direction can be adjusted, and the movement of the headrest in the seat front-rear direction can be restricted. Therefore, the effect of reducing the impact on the headrest 4 when the vehicle receives a collision from the rear can be obtained without affecting the practicality of the vehicle seat 1.
In the present embodiment, the fastening bracket 7 has wall portions 72R, 72L extending upward from both ends of the base portion 71 in the seat width direction. Thereby, the strength of the entire fastening bracket 7 is improved, and the headrest support portion 6 and the sheet metal 8 are more firmly connected by the fastening bracket 7. Therefore, when the vehicle receives a collision from the rear, the impact on the headrest 4 is further reduced, so that whiplash of the occupant can be further suppressed.
In the present embodiment, one end of the fastening bracket 7 is connected to the support bracket 6 as the headrest support portion 6 by welding. This ensures that the headrest support portion 6 and the sheet metal 8 are firmly connected, and the labor and time required for connection are reduced, as compared with a connection method in which the fastening bracket 7 and the headrest support portion 6 are connected using an intermediate member such as another fastener, thereby improving workability. Further, the number of components can be reduced by welding as described above, so that the cost can be reduced.
In the present embodiment, the other end of the fastening bracket 7 may be connected to the vehicle body (the sheet metal 8) by a mechanical fastener (a bolt 76 and a nut 77). This ensures that the headrest support portion 6 is firmly connected to the vehicle body (the metal plate 8), and the fastening bracket 7 is easily detached from the vehicle body, and the operation is simple when the fastening bracket 7 and the metal plate 8 are connected or disconnected.
