Abstract

A door latch apparatus for a door for a vehicle includes a first base member made of metal and including a striker receiving groove, a latch configured to be rotatable about a latch rotary shaft in an engagement direction in which the latch engages with the striker and a disengagement direction where the latch disengages from the striker, a second base member made of metal and arranged to face the first base member with the latch therebetween, the second base member fixed to the first base member, and a load receiving structure receiving an input load when the striker having entered into the striker receiving groove is biased towards the second base member, the load receiving structure receiving the input load with both a first load receiving portion extended from one base member towards the other base member, and a second load receiving portion provided at the other base member.

First claim

1 . A door latch apparatus for a door for a vehicle, the door latch apparatus comprising:
a first base member made of metal and including a striker receiving groove configured such that a striker enters into the striker receiving groove; a latch configured to be rotatable in two directions about a latch rotary shaft attached to the first base member, the two directions corresponding to an engagement direction in which the latch engages with the striker and a disengagement direction in which the latch disengages from the striker; a second base member made of metal and arranged to face the first base member with the latch interposed therebetween, the second base member being fixed to the first base member; and a load receiving structure receiving an input load in a case where the striker having entered into the striker receiving groove of the first base member is biased towards the second base member, the load receiving structure receiving the input load with both a first load receiving portion extended from one base member of the first base member and the second base member towards the other base member, and a second load receiving portion provided at the other base member.

2 . The door latch apparatus for the door for the vehicle according to claim 1 , wherein the load receiving structure is configured such that the first load receiving portion of the one base member and the second load receiving portion of the other base member are not connected to each other, and that each of the load receiving portions faces the striker which is in a state of having entered into the striker receiving groove.

3 . The door latch apparatus for the door for the vehicle according to claim 1 , wherein the load receiving structure is configured such that strength of the first load receiving portion of the first base member serving as the one base member exceeds strength of the second load receiving portion of the second base member serving as the other base member, and such that the load receiving structure comes into contact with the first load receiving portion prior to the second load receiving portion in a case where the striker which is in a state of having entered into the striker receiving groove is biased towards the second base member.

4 . The door latch apparatus for the door for the vehicle according to claim 3 , wherein the first load receiving portion is configured as a plate portion formed in an arch shape and including two extended pieces which are extended respectively from two different base end regions of the first base member and define an entering space for the striker, and a connection piece connecting extended ends of the respective two extended pieces to each other.

5 . The door latch apparatus for the door for the vehicle according to claim 4 , wherein the first base member includes a drawing portion at a portion which is at an outer side of the entering space and is adjacent to the extended piece.

6 . The door latch apparatus for the door for the vehicle according to claim 4 , wherein the first load receiving portion is configured to extend along a panel-extended-surface of a vehicle body panel at which the door for the vehicle is fitted in a case where the door for the vehicle is closed.
