rare. [f. KNEE sb. + -LET: cf. armlet, earlet.] A piece of armor or clothing protecting or covering the knee; spec., a genouillère.
a. 1843. Southey, Doctor, clxxxviii. (1848), 497. A necessary part of a suit of armour was distinguished by this name (genouillères) in the days of chivalry; and the article of dress which corresponds to it may be called kneelets, if for a new article we strike a new word.
1896. Westm. Gaz., 31 March, 3/2. This is, properly speaking, not a garter at all: it is a kneelet, if I may coin the term.
