Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and relates to a seat and vehicle that can realize multi-functional scene modes. Background Technology

[0002] As people drive and travel more frequently, their demand for comfortable car seats is also increasing. Currently, some car seats have the function of flipping back and flattening to connect with the seat cushion to form a bed in order to improve the comfort of passengers. However, the bed surface is not the seat surface that directly contacts the passenger, resulting in poor comfort. For example, Chinese patent CN208248017U discloses a utility model patent entitled "A Seat Assembly for Vehicles". This seat is a reclining front seat with extendable leg support. Although it can form a bed, it has the following disadvantages, including but not limited to: (1) the bed surface is uneven, which affects comfort; (2) the seat cushion cannot maintain a relatively low posture throughout the adjustment process, and the seat cushion arrangement occupies too much space. Chinese patent CN204398924U discloses a utility model patent entitled "A three-person sliding seat for vehicles that can be extended into a bed". The seat is a seat with a separate backrest design that can be manually or electrically extended into a bed. It has the following disadvantages, including but not limited to: (1) The length of the individual seat cushion and backrest spliced ​​together is too short, and the user's body cannot be fully supported, resulting in a lack of comfort; (2) The unlocking method mainly relies on the handle for unlocking, which has a low degree of automation.
