Abstract
A latch device includes a latch engageable with a rod portion of a striker, and is capable of transition to a locked state in which the latch is engaged with the rod portion and to an unlocked state in which the latch is disengaged from the rod portion, and includes a first shaft member that supports the latch in a manner that permits the latch to rotate, and a base member that supports the first shaft member. The base member is a unitary member which includes a first support wall disposed on one side of the latch and configured to support one end of the first shaft member, a second support wall disposed on an other side of the latch and configured to support an other end of the first shaft member, and a connecting wall that connects the first support wall and the second support wall.
Claims10
A vehicle seat comprising:
- a seat frame;
- a latch device;
- and
- a first fixing member that fixes the latch device to the seat frame, wherein the latch device comprises:
- a latch engageable with a rod portion provided on a vehicle, the latch device being configured to transition to a locked state in which the latch is engaged with the rod portion and to an unlocked state in which the latch is disengaged from the rod portion;
- a first shaft member that supports the latch in a manner that permits the latch to rotate;
- and
- a base member that supports the first shaft member,
- wherein the base member is formed as a one-piece member, made from a metal sheet, the one-piece member comprising a first support wall disposed on one side of the latch in a direction of a rotational axis of the latch and configured to support one end of the first shaft member, a second support wall disposed on an other side of the latch in the direction of the rotational axis and configured to support an other end of the first shaft member, and a connecting wall that connects the first support wall and the second support wall,
- wherein the latch has a through hole through which the first shaft member extends, and
- wherein the latch comprises an annular projection projecting from a periphery of the through hole in the direction of the rotational axis, a metal latch body, and a plastic cover that covers part of the metal latch body,
- wherein the annular projection is formed as part of the plastic cover and has a recess that is recessed from an outer periphery of the annular projection.
A method of manufacturing a vehicle seat, the method comprising:
- providing a seat frame;
- providing a latch device comprising:
- a latch engageable with a rod portion provided on a vehicle, the latch device being configured to transition to a locked state in which the latch is engaged with the rod portion and to an unlocked state in which the latch is disengaged from the rod portion,
- a first shaft member that supports the latch in a manner that permits the latch to rotate, and
- a base member that supports the first shaft member, the base member being formed as a one-piece member, made from a metal sheet, the one-piece member comprising a first support wall disposed on one side of the latch in a direction of a rotational axis of the latch and configured to support one end of the first shaft member, a second support wall disposed on an other side of the latch in the direction of the rotational axis and configured to support an other end of the first shaft member, and a connecting wall that connects the first support wall and the second support wall;
- and
- fixing the latch device to the seat frame by a first fixing member,
- wherein the latch has a through hole through which the first shaft member extends, and
- wherein the latch comprises an annular projection projecting from a periphery of the through hole in the direction of the rotational axis, a metal latch body, and a plastic cover that covers part of the metal latch body,
- wherein the annular projection is formed as part of the plastic cover and has a recess that is recessed from an outer periphery of the annular projection.
