A lighter actuated by a push-control member (24) which can move in a longitudinal direction, and which resists use by children, comprising a lighter-body (2) and lighting means comprising said push-control member. The push-control member (24) is guided in two essentially perpendicular directions, a longitudinal direction (36) in relation to the lighter body (2) and a transversedirection (38, 56, 60) in relation to the lighter body (2). The push-control member (24) has an abutment face (34, 46, 52, 53) which is normally opposite a counter-abutment surface (34, 44, 2) integral with the lighter-body (2), and a push-control member (24) is displaceable in the transverse direction (38, 56, 60) such that its abutment face is then in a non-active position relative to itscounter-abutment surface. Elastic means (40, 54, 58, 41, 62) comprising an elastic tongue member extending longitudinally and deformable transversely in accordance with transverse movement of the push-control member (24), act in a transverse direction (38, 56, 60) to return the abutment face of the push-control member to a position opposite the counter-abutment surface, means being provided to return the push-control member (24) into a position of rest in the longitudinal direction. Said elastic means may comprise a U-shaped metallic strip, one branch of which being elastically deformable, the second branch acting as an electrode forming electrical contact with the conductive material of piezoelectric lighting system.

Briquet actionné par un poussoir (24) déplacable longitudinalement et à l'éepreuve des enfants. Ce briquet comporte un corps de briquet (2) et des moyens d'allumage comprenant le poussoir. Le poussoir (24) est guidé dans deux directions essentiellement perpendiculaires, une première direction longitudinale (36) par rapport au corps du briquet (2) et une seconde direction transversale (38, 56, 60) par rapport à ce même corps (2). Il est muni d'une face de butée (34, 46, 52, 53) et d'une face de contre-butée (34, 44, 2) solidaire du corps du briquet (2). Il peut être déplacé selon la direction transversale (38, 56, 60) de telle sorte que sa face de butée soit alors en position effacée par rapport à sa face de contre-butée. Des moyens élastiques (40, 54, 58, 41, 62) comprenant une languette élastique longitudinale et déformable transversalement par le poussoir (24) déplacé transversalement agissent selon la direction transversale (38, 56, 60) pour ramener la face de butée du poussoir en vis-à-vis de la face de contre-butée et des moyens sont prévus pour rappeler le poussoir (24) en position de repos dans la direction longitudinale. Les moyens élastiques peuvent comprendre une bande métallique en U dont une branche est élastique et dont la seconde branche fait office d'électrode établissant un contact électrique avec le matériau conducteur d'un dispositif d'allumage piézoélectrique.
