Systems and methods for flipping a seat of a vehicle

A system for flipping a seat in a vehicle, comprising:

• a base member for the seat;
• a drive mechanism partially used for driving the base member to rotate around a first axis in a horizontal direction left and right relative to a seat occupant, wherein the first axis is centrally located in the base member;
• a first support member and a second support member of the seat, wherein a lower end of one side of the first support member is rotatably connected to an output end of the drive mechanism for driven rotation, and a lower end of the second support member is rotatably connected to an upper end of the first support member;
• a backrest member, whose left and right sides are located within the second support member and are rotatably connected with the second support member in a horizontal direction along a second axis, wherein the second axis is centrally positioned in the backrest member;
• a lock mechanism for locking and unlocking the backrest member with the second support member;
• a rotation mechanism;
• and
• a control module for sending a command to flip the seat;
• wherein the drive mechanism is activated by the command to rotate the first support member by a predetermined angle, and to rotate the base member in the same clockwise direction, wherein the rotation mechanism causes the second support member to rotate counterclockwise relative to the first support member, triggering the lock mechanism to unlock during rotation, and causing the backrest member to rotate 180° relative to the second support member before re-triggering the lock mechanism to lock the backrest member with the second support member, wherein the first support member, the second support member and the base member rotate synchronously, completing the flip of the seat to allow the occupant to sit in the opposite direction.

A vehicle, comprising:

• a vehicle body;
• and
• a system for flipping a seat in the vehicle, comprising:
• a base member for the seat;
• a drive mechanism partially used for driving the base member to rotate around a first axis in a horizontal direction left and right relative to a seat occupant, wherein the first axis is centrally located in the base member;
• a first support member and a second support member of the seat, wherein a lower end of one side of the first support member is rotatably connected to an output end of the drive mechanism for driven rotation, and a lower end of the second support member is rotatably connected to an upper end of the first support member;
• a backrest member, whose left and right sides are located within the second support member and are rotatably connected with the second support member in a horizontal direction along a second axis, wherein the second axis is centrally positioned in the backrest member;
• a lock mechanism for locking and unlocking the backrest member with the second support member;
• a rotation mechanism;
• a control module for sending a command to flip the seat;
• and
• a human interface device of the vehicle for entering the command;
• wherein the drive mechanism is activated by the command to rotate the first support member by a predetermined angle, and to rotate the base member in the same clockwise direction, wherein the rotation mechanism causes the second support member to rotate counterclockwise relative to the first support member, triggering the lock mechanism to unlock during rotation, and causing the backrest member to rotate 180° relative to the second support member before re-triggering the lock mechanism to lock the backrest member with the second support member, wherein the first support member, the second support member and the base member rotate synchronously, completing the flip of the seat to allow the occupant to sit in the opposite direction.
