In T2 ,T2and T2B+, if the original seat attachment are changed, these parts must either  be produced by a manufacturer approved by the FIA ??or comply with the following specifications (see drawing 253-65):

- supports must be attached tothe shell / chassis must have at least 4 mounting points per seat  using  bolts with a minimum diameter of 8mm and counterplate  in the drawing. The minimum area of ??contact between support, shell / chassis and counterplate will is  40 cm2 for each mounting point. If quick opening systems are used, they must be able to withstand horizontal and vertical forces of 18,000 N not applied simultaneously. If rails for adjusting the seat are used, they must be those originally supplied with the homologated car (T1B, T2) or with the seat.


  - The  seat must be attached  to the supportts via 4 monting points , 2 at the frontand  2 at the seat, using bolts with a minimum diameter of 8 mm and reinforcements integrated into the seat. Each mounting point  must be capableof withstanding   a force of 15 000 N applied in any direction.

  - The minimum thickness of the supports and counterplates be 3 mm for steel and 5 mm for light alloy materials. The minimum longitudinal dimension of each support is 6 cm.

All the occupants' seats must be FIA homologated

When using a cushion between the occupant and approved seat, this cushion is
have a maximum thickness of 50mm.
- Every seat occupants must be approved by the FIA ??(8855 Standards / 1999 or
8862/2009), and unaltered.

- Seats comply with FIA 8855/1999 standard:
Usage limit is 5 years from the date of manufacture indicated on
label required.
An extension of two years may be granted by the manufacturer and must be
indicated by an additional label.

the seat must be used in accordance with the seat
  manufacturer's instructions and with Technical List n°12.

- Seats comply with FIA 8862/2009 standard:
Usage limit is 10 years from the year of manufacture.
The use of certified with the seat brackets is mandatory.

   the seat must be used in accordance with the seat
   manufacturer's instructions and with Technical List n°40.

If a foam insert is used between the pilot and the homologated seat, a minimum lateral support at the pilot's head, shoulders and pelvis must be guaranteed as follows
- 230mm min. lateral head support following the plane of the head.
- 180mm min. to the lateral shoulder support of the seat following the plane of the shoulder.
- 100mm min. height to the lateral support of the basin of the seat according to the plan of the basin and on a length of 200mm min
This requirement must be verified using a parallelepiped template of dimensions X 200 x Y 150 x Z 100mm.


Application: All National and Regional events
Concerns: All car groups T2, T2B T2B +
If attachments or supports the original are changed, mounting on the shell / chassis as
Drawings 100 or 101 or 102 may be used.

6.1. Compulsory wearing two shoulder straps and a lap belt. These harnesses must comply with FIA standard No. 8854/98 or 8853/98. In addition, it is recommended that for competitions including public road open systems opening push button release.

Points of attachment to the hull or chassis: two for the lap strap, 2 (or 1 symmetrical headquarters) for the shoulder straps. It is possible to make a hole in a series of seat to allow the passage of a safety belt.

The anchor points of the production car (Group T2 and T2B ET T2B+) should be used.

If the mounting of the anchors is not possible, a new anchor points are installed in the shell or the chassis, one for each strap and separated as close as possible to the axis of the rear wheels for the shoulder straps. The shoulder straps can also be fixed to the rollcage or a strut bar with a loop, as well as being attached to anchor points higher belts before, or support or be attached to a transversal reinforcement welded to rear struts of the hoop.

In this case the use of a transversal reinforcement is subject to the following conditions:

- The transverse reinforcement will be a tube of at least 38 mm x 2.5 mm or 40 mm x 2 mm carbon steel, cold drawn seamless, a minimum tensile strength of 350 N/mm2.

- The height of this reinforcement must be such that the shoulder straps are, rearwardly, downwardly at an angle between 10 ° and 45 ° relative to the horizontal from the upper edge of the backrest an angle of 10 ° is recommended.

- Fixing straps loop is allowed, as well as by screws, but in the latter case an insert must be welded to each anchor point (see drawings 253-66 and 253-67 for dimensions). These inserts are positioned in the reinforcement and the straps will be attached by bolts M12 8.8 or 7/16 UNF.

ASNs may homologate attachment points located on the cage during the approval of the cage (see Homologation Regulations), provided they are tested.



The recommended geometrical locations of the anchor points are shown on drawing 253-65. The shoulder straps must be directed back down and should not be mounted to create an angle of 45 ° to the horizontal from the top edge of the case, and it is recommended not exceed 10 °.

The maximum angles to the axis of the seat are 20 ° divergent or convergent.

If possible, anchor originally fitted by the manufacturer of the car on the C should be used.

Anchor points leading to a higher angle relative to the horizontal must not be used unless the seat meets the FIA ??standard. In this case, the shoulder straps of the harness 4 points must be installed on the anchor points for rear seat lap belts fitted as original equipment by the manufacturer of the car.

For a 4-point belt, the shoulder straps are mounted so as to intersect symmetrically relative to the axis of the front seat.

A safety harness must not be installed on a seat without headrests or folder with integrated headrest (without opening between backrest and headrest).

Waist straps and crotch must not pass over the sides of the seat, but through the seat to wrap and hold the pelvic region over the greatest possible surface area. The lap straps must fit tightly in the hollow between the pelvic crest and the upper thigh. They should not focus on the abdominal area. To do this, set the seat can be pierced. We must ensure that the straps can be worn by rubbing against sharp edges.

If installation on the series anchorage is not possible for the shoulder straps and / or crotch new anchor points are installed in the shell or the chassis, as close as possible to the axis of the wheels back to the shoulder straps. If the installation is not possible, the shoulder straps can be attached or rely on a rear transversal arch attached to the anchor points or upper front belts.

Each anchor must withstand a load of 1470 daN 720 daN or for crotch straps. In the case of an anchor for two straps, the applied load will equal the sum of the required loads.

For each new anchor point is created, one will use a steel backing plate of at least 40 cm2 and at least 3 mm thick.


6.2.1 Principles of mounting to the chassis / monocoque:

1 - General mounting system: see drawing 253-62.

2 - Mounting system for the shoulder straps: see drawing 253-63.

3 - System crotch strap mounting: see drawing 253-64.


6.3. USE

A safety harness must be used in its configuration approval without modification or removal of parts, and in accordance with the manufacturer's instructions.

The efficiency and life safety belts are directly related to how they are installed, used and maintained.
The belts must be replaced after every severe collision and if they are cut, frayed or weakened if the straps by the action of sunlight or chemicals. It must also be replaced if metal parts or buckles are bent or rusted
