- said first buffer pocket (8) forms an overtravel stop (9) for said pawl (4);
- said pawl (4) is at least partially encased by a soundproofing material;
- and
- said pawl (4) abuts said overtravel stop (9) when said catch is rotated counterclockwise during closing of the latch up to a mechanical rotational limit of said catch (1).
