[0121] Figure 14 View “B” shown in the figure represents the portion where the rear channel brace 170, the channel portion 22, the channel reinforcement 130, and the center seat rear member 110 are joined. For example, the rear channel brace 170, the channel portion 22, the channel reinforcement 130, and the center seat rear member 110 are welded to stably support the mounting position of the center seat.

[0122] Figure 15 is a partial perspective view of the rear portion of the center seat mounting structure according to an embodiment.

[0123] The center seat mounting structure according to an embodiment can minimize the use of separate members for mounting the center seat.

[0124] In other words, the center seat mounting structure according to an embodiment can reduce the cost and weight by utilizing a general first row two-seat vehicle body platform structure and by employing or requiring the minimum number of separate members.

[0125] For example, by showing the structure of the front part in Figure 9 where the center seat front bracket 80 and the center seat front reinforcement 90 are not installed or assembled, and by showing the structure of the rear part in Figure 15 where the center seat rear member 110 and the center seat rear reinforcement 120 are not installed or assembled, a vehicle with the first row seat not having the center seat installed or assembled can be manufactured.

[0126] In addition, in the case where the front channel patch 140, the rear channel patch 150, the front channel brace 160, and the rear channel brace 170 are not installed or assembled, a vehicle with the first row seat not having the center seat installed can be manufactured.

[0127] Conversely, in order to produce a vehicle with the center seat installed or assembled, the center seat can be installed or assembled in the first row seat by installing or assembling the center seat front bracket 80 and the center seat rear member 110.

[0128] In addition, the center seat front reinforcement 90 and the center seat rear reinforcement 120 can be installed or assembled to support the center seat front bracket 80 and the center seat rear member 110.

[0129] In addition, the front channel patch 140, the rear channel patch 150, the front channel brace 160, and the rear channel brace 170 can be installed or assembled to support the center seat front bracket 80 and the center seat rear member 110.

[0130] As described above, the center seat mounting structure according to the embodiment minimizes the need for separate components for mounting the center seat, and enables the manufacture of vehicles with the center seat installed and vehicles without the center seat installed.

[0131] In addition, the center seat mounting structure according to the embodiment can reduce costs and weight by utilizing a general first row two-seat vehicle body platform structure and by adopting or requiring the least number of separate components.

[0132] In addition, the center seat mounting structure according to the embodiment can meet the regulations regarding seat belt holders by ensuring the strength of the structure for mounting the center seat.

[0133] In addition, the center seat mounting structure according to the embodiment can achieve the installation of the center seat by using only the least number of components, thereby increasing the degree of freedom in seat installation position and design.

[0134] In addition, in the center seat mounting structure according to the embodiment, when the center seat is not installed, the space available for the center console can be maximally ensured.

[0135] Although the technical concept of the present disclosure has been described in connection with presently regarded practical embodiments, it should be understood that the present disclosure is not limited to the described embodiments. On the contrary, the present disclosure aims to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
