Pedal assembly with a release mechanism
Embodiments described herein are directed to a pedal assembly. The pedal assembly includes a housing, a pedal arm, a retaining member, and a block. The pedal arm has an upper end. The upper end is pivotally coupled to the housing. The retaining member is slidably engaged within the housing. The retaining member has a first angled portion. A portion of the retaining member in communication with the upper end of the pedal arm. The block is slidably mounted within the housing and perpendicular to the first angled portion of the retaining member. The block has a second angled portion that is complimentary to the first angled portion. Upon an impact, the second angled portion slidably engages with the first angled portion, which causes the retaining member to move and release the upper end of the pedal arm from the housing.
1. A pedal assembly comprising:
a housing;
a pedal arm having an upper end pivotally coupled to the housing;
a retaining member slidably engaged within the housing, the retaining member having a first ramp portion relative to an upper surface of the retaining member, a portion of the retaining member in communication with the upper end of the pedal arm; and
a block slidably mounted within the housing and perpendicular to the first ramp portion of the retaining member, the block having a second ramp portion relative to a sidewall surface of the block, the second ramp portion is complimentary sloped to the first ramp portion,
wherein upon an impact, the second ramp portion of the block slidably engages with the first ramp portion which causes the retaining member to move and release the upper end of the pedal arm from the housing.
2. The pedal assembly of claim 1 , wherein a portion of the block extends beyond the housing to make contact with a portion of an instrument panel upon the impact.
3. The pedal assembly of claim 1 , wherein the retaining member is generally U-shaped having a base portion connecting a first leg spaced apart from a second leg.
4. The pedal assembly of claim 3 , wherein the first ramp portion of the retaining member is positioned within an upper surface of the base portion.
5. The pedal assembly of claim 3 , wherein:
the housing further includes a channel; and
a pair of bushings are each in communication with the upper end of the pedal arm, the pair of bushings are positioned within the channel.
6. The pedal assembly of claim 5 , wherein each one of the pair of bushings have an upper surface and each respective upper surface is in communication with the respective first leg and the second leg of the retaining member.
7. The pedal assembly of claim 5 , wherein upon the impact, the second ramp portion of the block slidably engages with the first ramp portion to cause the first leg and the second leg to displace which releases each one of the pair of bushings and the upper end of the pedal arm from the channel of the housing.
8. The pedal assembly of claim 5 , wherein each one of the pair of bushings are keyed to inhibit rotation within the channel.
9. The pedal assembly of claim 1 , further comprising:
a second pedal arm having a second upper end, the second upper end pivotally coupled to the housing.
10. A pedal assembly having impact features, the pedal assembly comprising:
a housing having a slot, a cavity, and a channel;
a pedal arm having an upper end, the upper end pivotally coupled to the housing within the channel;
a retaining member slidably engaged with the slot and positioned at least partially within the housing, the retaining member having a first ramp portion relative to an upper surface of the retaining member, the retaining member is in communication with the upper end of the pedal arm; and
a block slidably mounted within the cavity of the housing and positioned perpendicular to the retaining member, the block having a second ramp portion relative to a sidewall surface of the block, the second ramp portion is complimentary sloped to the first angled portion,
wherein upon an impact, the second ramp portion of the block slidably engages with the first ramp portion which causes the retaining member to move within the slot and releases the upper end of the pedal arm from the channel of the housing.
11. The pedal assembly of claim 10 , wherein the slot extends in a perpendicular direction with respect to the channel and the cavity.
12. The pedal assembly of claim 10 , wherein the retaining member is generally U-shaped having a base portion connecting a first leg spaced apart from a second leg.
13. The pedal assembly of claim 12 , wherein the base portion further includes a fastener that couples the retaining member to the housing, the fastener is configured to sheer when a predetermined amount of force is applied to the retaining member via the block.
14. The pedal assembly of claim 13 , wherein the first ramp portion of the retaining member is positioned within an upper surface of the base portion.
15. The pedal assembly of claim 13 , further comprising:
a pair of bushings positioned within the channel and in communication with the upper end of the pedal arm within the channel.
16. The pedal assembly of claim 15 , wherein each one of the pair of bushings have an upper surface and each respective upper surface is in communication with the respective first leg and the second leg of the retaining member.
17. The pedal assembly of claim 16 , wherein upon an impact, the second ramp portion of the block slidably engages with the first ramp portion to cause the first leg and the second leg of the retaining member to release each one of the pair of bushings and the upper end of the pedal arm from the channel of the housing.
18. The pedal assembly of claim 15 , wherein each one of the pair of bushings are keyed to inhibit rotation within the channel.
19. The pedal assembly of claim 10 , further comprising:
a second pedal arm having a second upper end, the second upper end pivotally coupled to the housing.
20. The pedal assembly of claim 19 , wherein the pedal arm and the second pedal arm are adjustable between a plurality of positions by a motor.
