中头盔（bascinet,bassinet或者basinet）是一种欧洲中世纪敞面战盔，典型配有锁子甲面罩(aventail)和带铰链的面罩。

14世纪早期的版本没有面罩，而是戴在一个更大的头盔里面（头盔中的头盔）。在骑兵第一次使用骑枪进行冲锋之后骑兵们展开肉搏战，外面的“更大的头盔”就被扔掉，因为它妨碍士兵呼吸而且影响视线。所以在这种战术中，里面还戴着一个小头盔是非常占优势的。

头盔敞面部分的边缘具有很多小孔，用来装上锁子甲面罩来保护下巴、脖子和肩膀。

The bascinet — also bassinet, basinet, or bazineto — was a Medieval European open-faced military helmet. It evolved from a type of iron or steel skullcap, but had a more pointed apex to the skull, and it extended downwards at the rear and sides to afford protection for the neck. A mail curtain ("camail" or aventail) was usually attached to the lower edge of the helmet to protect the throat, neck and shoulders. A visor (face guard) was often employed from ca. 1330 to protect the exposed face. Early in the fifteenth century, the camail began to be replaced by a plate metal gorget, giving rise to the so-called "great bascinet".
