Ducato / Jumper / Boxer passenger seat
Conversion passenger bench seat (A) to single seat (B)
25.07.2019
Today I was seeking some clarification via telephone – with little result.
I’d love to use a current model Jumper in the flavor L4H3, those are being offered on the usual web sites for around € 25,000. Those are already fitted as a Heavy 35 chassis with hitch, A/C, etc.
Unfortunately, the offered vehicles are bought up from large orders and are exclusively fitted with a passenger bench seat and I really want a single seat.
So – what are the considerations (for factory seats)?
Telephone conversation with my friendly FIAT dealer in Herne:
A is – according to the dealer – attached via 6 bolts in the passenger area. B is – according to the dealer – attached via 4 bolts.
- Will the bolt pattern fit using 4 of the 6 bolt holes?
Dealer: “One would have to measure that.”
The seatbelt
- Belt will continue to be used from the B-pillar, receiver attached to seat on LHS?
Dealer: “Yes.”
Passenger airbag system
- Is there a difference in the utilized airbags between system A and B?
Dealer: “No, the systems SHOULD not differ.”
One seat less, that will perhaps send faults due to open circuits to the ECU?
- Can the ECU be convinced to ignore the missing data of the missing middle seat?
Dealer: “Perhaps. If that does not work on a program level, then just bridge the plug of the middle seat with a resistor.”
Telephone conversation with a “TÜV Nord” technical expert (The TÜV is the licensing body in Germany for all technical specifications):
Boltholes for B have a different boltpattern from A
- Seats are factory mounted using the frame or a subframe member on the underside of the passenger area. If the boltpattern differs, is it permissable to fit a suitable subframe in order to attach the seat?
TÜV: “No, as these factory attachment points and the seats are part of the original certification. Alterations are not permitted.”
O.K., this means a dealer visit, to verify attachment and bolt pattern.
Stay tuned.
