Innenraum: Fahrersitzlehne Belueftung DIY

[Erich]

Patrick von roadfly hat hier gerade seine selbstgebaute Rueckenbelueftung an seinem 750 vorgestellt. Sieht fast aus wie im space shuttle



Just have been experimenting with some ducting to help ventilate my back from the leather seat. Usually around 40 minutes into my commute especially when I slow down from freeway speed and exit onto city street, I would find the seatback very warm. At first I thought the seat heater switch was broken (it did, and I cleaned and fix it), but it is just lack of ventilation on summer days.

Here is what I just did to modify the ducting to redirect the rear passenger air outlet to the driver seat. Quite crudgy but seems to serve the purpose in the last two days of test. Despite the air flow being pretty low (much lower than what comes out from the front vents) my back remains cool. Ironically, having some odd thing at the back also make me not put all my weight onto the seatback, which results in more space for ventilation.

Does anyone know how to increase the proportion of air flow to the rear grill?

Hmmmh, aber die Frage wie er den Durchfluss der Luft nach hinten erhoehen kann, kann ich auch nicht beantworten.
