Passengers in the rear seat behind the front passenger are finding it difficult to fasten the seat belt, especially old or, shall we say, stouter folk. The sound of the continuous alarm often entails me going to their assistance.
I have tried one firm's but the plastic on the existing belt tongue fouled the extender and fortunately they refunded me.
Anyone purchased one that works?

Belt should extend out to cover the very stout. Does it extend as far as the other side? Should do.
