A device for longitudinally adjusting motor vehicle seats, of the type comprising a pair of fixed guides (10) rigid with the vehicle floor and a pair of mobile guides (12) rigid with the seat and slidable along the fixed guides. Between at least one fixed guide and the respective mobile guide there is interposed a spring (44) rigidly fixed to the mobile guide and configured such that under normal operating conditions it engages in toothing (48) on the fixed guide to lock the mobile guide in position. A manually operated lever (54) is provided which acts on the spring (44) to disengage it from the toothing (48) on the fixed guide and release the mobile guide.

The ignition unit includes a support housing containing two ignition coils each for the connection to at least one, and preferably two, associated spark plugs. Each ignition coil comprises a primary winding and a second winding disposed around the end arms of a magnetic core or circuit formed by only two packs of plates juxtaposed so that together they form essentially a figure-of-8 shape. The packs of plates are identical, essentially E-shaped and are placed close together, face-to-face, so that together they form a squared figure-of-8 shape. Each of the packs of plates has a notch which extends from the back of the E into its central arm and almost up to the end of the free end thereof. Conveniently, inserts of non-magnetic material are disposed in the notches in the packs of plates.
