(14) As illustrated in FIGS. 2 to 4, the Carl punching system 100 for a vehicle seat cover according to the present disclosure includes:

(15) a base 102;

(16) guides 104 disposed on the top surface of the base 102 at predetermined distances from each other;

(17) a controller 106 disposed on an outer surface portion of the base 102 to control the Carl punching system for a vehicle seat, according to a preset program;

(18) a Carl punching unit 108 located on the central portion of the top surface of the base 102 to punch ventilation holes in a seat cover according to a design desired by a user; and

(19) a press 110 disposed on the guides 104 to be slidable up or down and electrically connected to the controller 106 to press the Carl punching unit 108 located on the central portion of the top surface of the base 102 in response to a control signal from the controller 106.

(20) As illustrated in FIGS. 5 and 6, the Carl punching unit 108 includes:

(21) a Carl punching plate 112 having a plurality of through-holes;

(22) Carl punching pins 114 interference-fitted into the through-holes of the Carl punching plate 112 and protruding from the top surface of the Carl punching plate 112 to punch ventilation holes in a seat cover; and

(23) a support plate 116 closely fixed to the bottom surface of the Carl punching plate 112 to support the Carl punching plate 112, with through-holes corresponding to the through-holes of the Carl punching plate 112 being formed in the support plate 116;

(24) Here, the through-holes of the support plate 116 are located on the same vertical lines as the through-holes of the Carl punching plate 112, with the inner diameter of the through-holes of the support plate 116 being smaller than the inner diameter of the through-holes of the Carl punching plate 112.

(25) In addition, the Carl punching pins 114 are comprised of groups of Carl punching pins (e.g. a first group, a second group, a third group, . . . , and Nth group of Carl punching pins),

(26) which are interference-fitted into the through-holes of the Carl punching plate 112, such that the ventilation holes can be punched in the seat cover in the design desired by the user.
