Seat assembly and method of assembling a seat

A seat assembly comprising a seat back assembly and a support frame, the support frame comprising a first side rail and a second side rail, the seat assembly further comprising:

• a first pin comprising a first lug, the first pin being connected to the first side rail of the support frame;
• a second pin comprising a second lug, the second pin being connected to the second side rail of the support frame;
• the seat back assembly comprising a first opening comprising a first recess corresponding to the first lug, the first opening being formed in a first side of the seat back assembly for receiving the first pin, and a second opening comprising a second recess corresponding to the second lug, the second opening being formed in a second side of the seat back assembly opposite the first side for receiving the second pin,
• wherein the first opening is configured to receive the first pin when the seat back assembly is rotated to align the first recess with the first lug, and the second opening is configured to receive the second pin when the seat back assembly is rotated to align the second recess with the second lug.

A seat assembly comprising a seat back assembly and a support frame, the support frame comprising a first side rail and a second side rail, the seat assembly further comprising:

• a first pin comprising a first lug, the first pin being connected to the first side rail of the support frame;
• a second pin comprising a second lug, the second pin being connected to the second side rail of the support frame;
• the seat back assembly comprising a first opening comprising a first recess corresponding to the first lug, the first opening being formed in a first side of the seat back assembly for receiving the first pin, and a second opening comprising a second recess corresponding to the second lug, the second opening being formed in a second side of the seat back assembly opposite the first side for receiving the second pin,
• wherein the seat back assembly is rotatable around the first pin to a position where the first lug is no longer aligned with the first recess, thereby preventing the first pin from being withdrawn from the first opening.

• wherein the seat assembly further comprises a third pin connected to the first side rail of the support frame and a fourth pin connected to the second side rail of the support frame, and wherein the seat assembly further comprises a first lower seat fixing connected to the first side of the seat back assembly and a second lower seat fixing connected to the second side of the seat back assembly, and wherein the third pin is connected to the first lower seat fixing and the fourth pin is connected to the second lower seat fixing.

A seat assembly comprising a seat back assembly and a support frame, the support frame comprising a first side rail and a second side rail, the seat assembly further comprising:

• a first pin comprising a first lug, the first pin being connected to the seat back assembly;
• a second pin comprising a second lug, the second pin being connected to a second side of the seat back assembly opposite to the first side;
• the support frame comprising a first opening comprising a first recess corresponding to the first lug, the first opening being formed in the first side rail for receiving the first pin, and a second opening comprising a second recess corresponding to the second lug, the second opening being formed in the second side rail for receiving the second pin,
• wherein the seat back assembly is rotatable to a position where the first lug is no longer aligned with the first recess, thereby preventing the first pin from being withdrawn from the first opening.

A method of assembling a seat comprising a seat back assembly and a support frame, the seat back assembly comprising a first side and a second side, the support frame comprising a first side rail and a second side rail, the method comprising:

• aligning a first pin connected to the first side of the seat back assembly with a corresponding first opening in the first side rail such that a first cooperating formation formed on the first pin is aligned with a corresponding second cooperating formation formed in an edge of the first opening;
• inserting the first pin into the first opening until a tip of a second pin connected to the second side of the seat back assembly opposite to the first side clears the second side rail;
• aligning the tip of the second pin with a second opening formed in the second side rail opposite to the first side rail;
• inserting the second pin into the second opening such that the seat back assembly is supported in the support frame by the first and second pins;
• and
• rotating the seat back assembly so that the first cooperating formation is no longer aligned with the corresponding second cooperating formation thereby preventing the first pin being withdrawn from the first opening and securing the seat back assembly to the support frame.
